First Upper Valley Brain Bee

First Upper Valley Brain Bee

Brain_bee_1_edited

Neurology professor Dr. Rand Swenson shows participants a human brain specimen at one of the activity stations.

Last weekend, over twenty high school students from around the area convened in the Class of 1978 Life Sciences Center for the first Upper Valley Brain Bee. Hosted by the Neuroscience Center at Dartmouth  and the Society for Neuroscience New Hampshire Chapter, this event would not have been possible without the hard work of Marie Onakomaiya and Alex Bender, the two graduate students responsible for envisioning and organizing this outreach project. Dr. Michelle Sama, coordinator of the Neuroscience Center at Dartmouth, also played a key role in orchestrating the event.

The competition was advertised to high school students throughout the entire Upper Valley, and ultimately students from six different schools competed. Weeks prior to the competition, Onakomaiya and Bender visited these schools to host “Brain Boot Camps” in which students were taught basic neuroscience and neuroanatomy and provided with study materials. After many weeks of preparation, the brainy students were ready to show off their neuroscience knowledge.

In round one of the competition, participants completed a short quiz, identified brain structures on real human brains, and diagnosed “patients” played by volunteers from the Dartmouth neuroscience community. Afterwards, the students had a break for lunch and visited a variety of activity stations run by professors from the medical school. Dr. Rand Swenson showed students brain specimens, Dr. Jeff Cohen and Dr. Alissa Thomas taught participants how to conduct a neurological exam on a patient, and Dr. Olga Emery provided demonstrations illustrating various brain functions. Meanwhile, Dr. Michelle Sama ran a “Color Your Brain” station for younger attendees. These activities concluded with a talk about Parkinson’s disease from neurology professor, Dr. Stephen Lee.

Having patiently waited long enough, the top five scorers from the first round were announced and brought up to the front of the room to compete in round two. This culminating phase was structured similar to a spelling bee: competitors answered questions from three different categories and were eliminated after responding to two consecutive questions incorrectly. Questions were asked by the judges of the event, four members of the Dartmouth neuroscience community (Dr. Allan Gulledge, Dr. Barbara Jobst, Dr. Jeremy Barry, and myself).

Dr. Hermes Yeh, the MC for the event, congratulates first place winner Jane Plomp, a 9th grader from Lebanon High School.

Jane Plomp, a 9th grader from Lebanon High School, took first place and will have the opportunity to compete in the National Brain Bee held in Washington, DC, next March. Molly Cornell, an 11th grader from Hanover High School, won second place, and Morgan Keller, a 12th grader from Lebanon High School, won third place.

Onakomaiya and Bender certainly accomplished their initial goal, which was “to introduce neuroscience to local high school students and provide a way for them to have fun learning about the brain,” says Bender. Based on everyone’s fantastic performance throughout the competition, it is evident that participants learned a great deal of information. Onakomaiya and Bender received a lot of positive feedback and hope that the Upper Valley Brain Bee will become a yearly tradition here at Dartmouth. Onakomaiya notes that “this year’s participants have already expressed interest in doing it again next year and will be recruiting their friends to join them.”

Alumni Research Award Recipient, Tyler Pavlowich

Alumni Research Award Recipient, Tyler Pavlowich

Coral reef ecosystems harbor tremendous biodiversity, perform important functions in the biogeochemical cycles of the planet, and provide the foundation upon which humans create unique and diverse relationships with nature.

In the summer of 2012, I traveled to Buen Hombre, Dominican Republic—a community of 600 residents on the northwestern coast of the country—to assess the status and functioning of coral reef fisheries accessed by artisanal fishermen. With the help of an undergraduate research assistant, Molly Wilson ’13, I performed fish-community surveys, benthic assessments, catch surveys, and social research on how the fishing system in Buen Hombre operates.

Thanks to the scuba equipment purchased with the Alumni Research Award, I was able to sample deeper reef sites that play an important role in the ecological dynamics of the area. We found that nearshore reefs are heavily exploited to the point that some areas have collapsed into an unhealthy, algae-dominated state.

Herbivorous fish maintain coral health by clearing away macro-algae that can outcompete slow-growing hard corals for space. This presents a major challenge for fisheries management because parrotfish, the Caribbean’s most abundant and effective herbivore, currently comprise at least fifty percent of fishermen’s catch in Buen Hombre.

The Alumni Research Award was an integral part of my experience in Buen Hombre, allowing me to perform more thorough and productive research. My future work will include modeling fish population dynamics to help the community and resource managers establish harvest guidelines and promote ecosystem recovery.

Meet the GSC Executive Board: Julia Bradley-Cook

Meet the GSC Executive Board: Julia Bradley-Cook

The Graduate Forum will be running a series of articles profiling the new Graduate Student Council. The GSC elections were held back on May 1st. As the new board members get underway in their positions, we’d like to take an opportunity to congratulate them on their elections and to highlight their hopes for the year ahead. We’re getting started with Julia Bradley-Cook, the new President of the Graduate Student Council.

Julia is a fourth year PhD candidate in the Ecology and Evolutionary Biology Department (EEB) who has already made a huge impact on graduate life at Dartmouth. Julia served as the Academic Chair on the exec board in 2011-12 and was the academic representative for the EEB Department in 2010-2011. Julia was instrumental in launching the popular “Nerd Night” events and the Graduate Pub Nights.

Originally from New York, Julia went to college at Grinnell College in Iowa, where she majored in Biology. Julia’s focus of study is carbon cycling in arctic soil. Julia explained that there is a high concentration of carbon in article soil, and that this carbon has a slow decomposition rate. This has serious implications for the way in which we see carbon cycles in relationship to climate change. Her research has taken her to the tundra in Greenland, where she’ll be for two months in the summer term.

Before coming to Dartmouth Julia worked in Nambia with an NGO, a job that exposed her to research and policy relationships. This was something she considers to be a valuable learning experience – one that encouraged her to enhance her research skills. Her ultimate aim is to work in the field, finding ways to push for policy that’s rooted in research science.

Julia is taking up her office in an exciting time of Dartmouth College’s history. Julia is ambitious about asserting the importance of the graduate community to the College’s administration while the Presidential transition is taking place. Among her primary policy initiatives are, to continue the pressure on the administration to provide dental care for graduate students, to lobby for day-care rights for graduate students, and to work with the administration on the on-going development of a graduate student space, which can be set aside for the enhancement of the graduate community.

In order to realize these goals, Julia intends to work closely with the college’s administration, encouraging dialogue and helping to facilitate the most effective means to meet graduate students’ needs. At the same time she wants to mobilize the graduate community to voice and take action to address their concerns. Reflecting on the importance of this aspect of improving services for students, Julia remarked: “I really value the graduate community. In many ways, we are our own best resource for advocacy.”

Outside of her studies and the GSC, Julia enjoys sports and outdoor activities. She plays center-back on her co-ed soccer team, Discofeet. She also tries to finds time to canoe and travel, as well as enjoying the company of her peers in the graduate community.

The Graduate Forum congratulates Julia on her election and wishes her the best for her term as president!

Teaching Assistant Awards series: Morgan Thompson

Teaching Assistant Awards series: Morgan Thompson

The Graduate Forum is proud to announce the winners of the Graduate Teaching Awards. The hard working students are Patricia Cahn in the Math department, April Daigle in Chemistry and Morgan Thompson, Biochemistry.

A fifth year student in the Bio-Chemistry PhD program, Morgan’s graduate research focus is on proteins. This interest has followed her from her undergraduate major in Bio-Medical Engineering at Boston University. To be more precise, how specific proteins interact with one another and function to cause the movement of cells within the Body. This research will further our understanding of how cancer cells move throughout the body and could affect the way we look at, treat and manage different cancers.

Whilst research was her motivation for coming to Dartmouth, Morgan also embraced teaching, and found she had a passion for it. The requirement for a PhD student in her program was for one term as a teaching assistant; Morgan volunteered for three more. She became attracted to her ability as a TA to influence the way in which courses were taught whilst working directly with the students. This including rewriting some of the course lab manuals as well as setting up labs for both an introductory biology and chemistry courses and a higher-level biology/chemistry course.

Contributing in this way allowed Morgan to do more of what she loved. She enthusiastically guided me through me through her graduate career path, telling me that she was grateful for the opportunity to put more into her teaching and education at Dartmouth. When asked about her reactions to receiving the Graduate Teaching Award, Morgan commented, “…its exciting, its nice to recognized for all the hard work.”

She has also found the experience has helped her develop skills for a career in teaching and is thankful to her advisor Professor Jon Kull for being supportive and allowing her to pursue what she was passionate about.

Aside from teaching at Dartmouth, Morgan extended her talents to the wider Upper Valley community. She was awarded a GK12 fellowship, which gave her funding for research and the opportunity to teach science to 6th graders. Because Morgan is from the area, she puts a lot of  value in the way Dartmouth is contributing to the region. In her words:

“It is important for the wider community outside of Dartmouth College to know that we care.”

And indeed, it is great to hear about Dartmouth students contributing to the local community, fostering a spirit of mutual aid. The local community has recognized her contributions; last year the Valley News featured an article about her dedication to teaching science in the area. Furthermore there is the unsung appreciate from all the students she has helped foster an interest in the sciences.

Following the completion of her thesis, Morgan is going to continue her passion for teaching Chemistry and Biology at a high school in New Jersey. Congratulations again Morgan. We wish her all the luck and success in her career.

Croasdale Award: Matt Cain

Croasdale Award: Matt Cain

The Hannah Croasdale Award for academic excellence is awarded annually to the graduating PhD recipient who best exemplifies the qualities of a scholar. This individual possesses personal qualities of intellectual curiosity, dedication, and commitment to the pursuit of new knowledge and to teaching, as well as a sense of social responsibility to the community of scholars. The award recipient is selected by The Dean of Graduate Studies.

Since January, Matt Cain has been conducting postdoctoral research at the Massachusetts Institute of Technology (MIT) under the guidance of Prof. Dick Schrock. A graduating doctoral student in Chemistry, Matt was selected as one of this year’s recipients of the Hannah Croasdale Award because of the excellence of his thesis research at Dartmouth, as well as his involvement in undergraduate teaching.

At MIT, Matt is researching how dinitrogen (N2) can be reduced to ammonia (NH3) through the addition of protons and electrons using a Molybdenum-based catalyst. While Matt has only been conducting this research for six months, the practical applications of reducing dinitrogen into ammonia are far-reaching: in its gaseous state, nitrogen is readily available in the Earth’s atmosphere, and ammonia is one of the basic ingredients in the production of fertilizer. Thus, the long-term goals of Matt’s postdoctoral studies are to find a cheap method to produce basic fertilizers for agriculture using nitrogen as a feedstock, which would help a number of third-world countries grow enough food to feed larger portions of their populations.

“The end goal of my postdoctoral research is to alleviate world hunger by finding a cheap, efficient way to manufacture basic fertilizers,” explains Matt. “While I doubt this large-scale problem will be solved in the foreseeable future, this research is addressing the issue head on, and I have confidence that my efforts will positively impact a number of remote, agrarian communities in the coming years.”

A former member of Prof. David Glueck’s lab, Matt’s doctoral research at Dartmouth addressed some fundamental problems in chemistry.  His doctoral dissertation, titled Cu(I)-Catalyzed P-C Bond Formation and the Synthesis of C3- and C1-Symmetric P-Stereogenic Triphosphine Ligands, investigated how copper–a cheap, environmentally-friendly metal—could catalyze the synthesis of chiral ligands, which are used by pharmaceutical companies to manufacture more “pure” drugs with fewer side effects.

“The chemical structures of some prescription drugs give them the potential to effect a patient’s body in more than one way. A famous example of this is the drug Thalidomide, which was prescribed to treat morning sickness in the late 50s. However, by the early 60s, Thalidomide was found to cause birth defects, and was withdrawn from the US market in 1961—years later, a connection between the chemical structure of Thalidomide and these birth defects was discovered. Thus, the graduate research I conducted at Dartmouth seeks to make drugs more pure, and helps reduce the number of potential side effects caused by their use.”

During his time at Dartmouth, Matt worked as a teaching assistant for five classes including several of the school’s general chemistry courses—Chemistry 5, Chemistry 6, Chemistry 10 (an Honors course), as well as Chemistry  64 for two terms.  Like all chemistry graduate students, Matt completed each of the training courses required by his department before setting foot in the classroom.

“I really enjoyed working as a Teaching Assistant,” says Matt. “In the classroom I explained a number of scientific concepts to undergraduates, and helped them conduct research experiments. While I finished my teaching obligations early in my doctoral career, working as a Teaching Assistant really defined my time at Dartmouth.”

Originally from Congers, NY, Matt received a B.S. in Chemistry from SUNY Geneseo in 2007, and started his doctoral studies at Dartmouth the summer after he graduated from Geneseo. As an undergraduate, Matt examined the luminescent properties of hetrobimeallic metal complexes, which are used in the production of Light Emitting Diodes (LEDs).

Congratulations, Matt!

The 85 percent – Marcella Lucas

The 85 percent – Marcella Lucas

The Student Notebook essay offers insight or opinion from a Dartmouth student or trainee. Marcella Lucas is a Ph.D. student in the Program in Experimental and Molecular Medicine. She was president of the Graduate Student Council in 2010-2011 and is now a coordinator of the International Graduate Mentoring Program. She is currently completing her Ph.D. and plans to pursue a career in health-care consulting.

 After three years studying biochemistry at the University of Bath in the United Kingdom, an additional year as a scientific intern at Dartmouth-Hitchcock’s Norris Cotton Cancer Center, and three years as a Ph.D. student, I have a lot of experience doing research.

My current research, though, is not going to end up in a scientific journal. Like many Ph.D. students, I am exploring what I might do with the advanced degree I will eventually receive.

Only about 15% of people who earn a Ph.D. in the sciences will become a tenured faculty member. So what happens to the other 85%? What happens to Ph.D. students who decide that academia is not for them? The truth is that their options are endless, but Ph.D. students often underestimate the importance of their degree, how much they have to offer, and the opportunities available to them outside academia.

If you ask Ph.D. candidates what they plan to do after completing their degree, you will likely hear that they are going to look for a postdoctoral position—or “postdoc.” After all, that is traditionally what new Ph.D.’s do. After two or perhaps three postdocs, maybe they will become a junior faculty member and start climbing the academic ladder.

At some point along the way, however, many students realize that they do not want to follow the traditional route and become an academic scientist—and I’m one of them. That’s why as I have pursued my scientific research, I have also worked on professional development. My extracurricular activities over the past few years have enriched my experience at Dartmouth. They have also helped me to understand my strengths and weaknesses and given me better insight into what might make me competitive on the job market.

“Put Your Science to Work: Practical Career Advice for Early Career Scientists”

“Put Your Science to Work: Practical Career Advice for Early Career Scientists”

 For many PhD students, there is often a tension between the development of their skills as scientists alongside skills that can serve them outside of academia.  Peter Fiske, Chief Technology Officer of PAX Mixer Inc. and PAX Water Technologies, recently visited Dartmouth to speak with graduate students about career development options for PhDs.

In his column at ScienceCareers.org, entitled “Opportunities,” Fiske regularly provides practical career advice for young scientists, as well as tips on how to navigate relationships both in the academic and private sectors. After describing his own career trajectory after earning his PhD from Stanford in the mid-1990s, Fiske explained that while his career path has been “unusual” for a geophysicist, it has nevertheless been “highly stimulating and enjoyable.”

“There’s a great tradition of cooperation in the scientific community,” Fiske noted, adding that he benefitted from numerous mentors and received lots of sage advice that he relishes passing on.

While a life in science can be very exciting, Fiske said that most academic institutions unfortunately still tend to enforce many of the “older” characteristics of an academic lifestyle (passivity versus entrepreneurship; age over experience, etc.) instead of the valuable traits that appeal to the private sector.  Transferable skills such as the ability to function in a variety of environments and roles, the ability to teach skills and counsel others, independently conceive and design complex projects, and problem-solve are all qualities that PhDs possess that are highly attractive to potential employers, said Fiske.

As scientists, “we don’t get very good career advice,” explained Fiske, who added that nearly 80% of PhDs don’t stay in academia.

“[It’s] important to unpack the social and cultural stereotypes that exist for PhDs,” Fiske explained, so that graduate students can accurately address their perceived weaknesses from the ‘outside’ world.  In what he termed, “The Curse of Being Smart,” Fiske outlined certain challenges that PhDs face in a career transition from academia, such as the failure to appreciate other forms of intelligence apart from a high-level academic skill set.

“We tend to immediate discount people from different pedagogical backgrounds,” explained Fiske, noting the penchant for PhDs to overemphasize their skills sets over their interpersonal relationships or emotional intelligence.  According to Fiske, this “curse” of being smart comes from academics who are used to being exceptional and don’t like to be unsuccessful, and thus often fail to ask very basic questions.

“You spend your time being technical people,” Fiske told the graduate students.  “Learn how to be effective.”

Fiske’s “80:10:10” rule illustrates his insistence on graduate students taking the reigns over their own career.  For Fiske, the rule exemplifies the importance of learning “the art of selectively blowing stuff off,” and represents a way in which graduate students can prioritize their own professional development.  The rule advises devoting eighty percent of your work time to all of academic “stuff you need to do.” According to Fiske, the daily tasks of research should be accomplished during this majority portion.  Ten percent of your time should be focused solely on your own professional development, and on strengthening yourself as an executive and as a professional. The remaining ten percent of working hours should be spent attending conferences and building a professional circle through networking.  If this networking isn’t automatically built into your schedule, Fiske insists, “it won’t happen otherwise.”

While many PhD students are uncomfortable with the concept of networking, Fiske pointed out that informational interviewing is an extremely useful tool to learn more about a specific industry and typical career path. According to Fiske, PhD students can use these interviews to ask “sticky questions” about future trends on hiring, salaries, workload, etc. that might be inappropriate to ask during a typical job interview.  An additional bonus of a successful informational interview is that the person being interviewed becomes a part of your professional network—and could be a valuable contact when you do start your job search.

For Fiske, virtually every job search should start with an honest and frank self-assessment.  Asking yourself what your interests are, what skills you have, what type of work style you prefer, etc., can help you determine not only what you are good at, but what you actually enjoy doing on a daily basis.  To get started on this self-assessment, Fiske recommends that students make a two-column list of everything that they like and dislike about their academic career, and then assign priorities of what they value the most and the least.  According to Fiske, the exercise helps students tangibly see their own values, as well as how their interests and skill affect their work and the workplace.

“In general, we share the same positives and negatives, but our ranked lists are very individualized,” said Fiske, who notes that this distinction is important because it shows that academia’s tendency to try to make the same model of science fit for everyone is not realistic. In fact, said Fiske, the acknowledgement of these differences is critical to one’s personal happiness.

“If you don’t like what you do for a living, you probably wont be very good at it!” he noted.

But what about those graduate students who aren’t graduating any time soon?  Fiske advises that every student, regardless of what point they are at in their graduate career, construct a brief professional biography.

“Careers only look good in the review mirror,” said Fiske, noting that the process of thinking about your professional and academic highlights can enable you to hone in on and highlight your personal strengths. Students should also consider investing in quality business cards that can be distributed at professional conferences, talks and events, an undertaking that Fiske calls an “act of professional courtesy.”

According to Fiske, the purpose of a resume is to get an interview as opposed to a job, and stressed that it is more of a screening device than anything else.

As a description of those past experiences that are most relevant to the position being sought, a resume is as much about where you are going as where you have been. When applying to jobs, PhD applicants should post a resume and cover letter specifically tailored to each job opening.  Fiske advises applicants to use the actual words in the job description as often as possible in your own application materials, and to try to highlight your own experiences that best match with the stated qualities and background of the desired candidate.

When that coveted job offer finally does roll in, Fiske notes that it is important to consider a variety of options and factors beyond the salary. Factors such as health care, schedule of raises, bonus and commission plan, stock options, paid parking, amount of vacation days, relocation allowances, and employee education/tuition reimbursement, etc., are all ‘off-value’ terms that are often more easily negotiated than a base salary, which is generally more inflexible.

According to Fiske, the mere process of exploration itself is extremely empowering as a scientist, regardless of whether they stay in academia or not.

“I believe that technically trained individuals have enormous opportunity to improve the world,” said Fiske.

Dartmouth Researchers Are Learning How Exercise Affects the Brain

Dartmouth Researchers Are Learning How Exercise Affects the Brain

Michael Hopkins, winner of the 2009 Graduate Community award, and his advisor, David Bucci

Exercise clears the mind. It gets the blood pumping and more oxygen is delivered to the brain. This is familiar territory, but Dartmouth’s David Bucci thinks there is much more going on.

“In the last several years there have been data suggesting that neurobiological changes are happening—[there are] very brain-specific mechanisms at work here,” says Bucci, an associate professor in the Department of Psychological and Brain Sciences.

From his studies, Bucci and his collaborators have revealed important new findings:

  • The effects of exercise are different on memory as well as on the brain, depending on whether the exerciser is an adolescent or an adult.
  • A gene has been identified which seems to mediate the degree to which exercise has a beneficial effect. This has implications for the potential use of exercise as an intervention for mental illness.

For more about the research being conducted by both graduate and undergraduate students in Bucci’s lab, visit the Dartmouth Now.

Grad Student Spotlight: Nicholas Tito

Grad Student Spotlight: Nicholas Tito

Originally from Kennebunkport, Maine, Nicholas Tito is a fourth-year PhD candidate in Chemistry. Nick’s graduate research examines the thermodynamics of polymers and focuses on when these materials are in their “glass” form. Through his involvement with the Gordon Research Seminar in Polymer Physics—a student-run conference that is held every two years—and the German JCF-Frühjahrssymposium, Nick has worked to bring graduate students together to learn about one another’s research.

“Currently, I’m serving as the Associate Chair for this year’s Polymer Physics Gordon Research Seminar, which is being held at Mount Holyoke College. The Gordon Seminars are entirely student run, and feature student talks and poster sessions along with a keynote speaker—usually a professor—whose research aligns with the conference topic,” explains Nick. “The Chair is a graduate student at Penn State, and I’ve communicated regularly with her while planning this year’s Gordon Seminar.”

In March, Nick joined a group of chemistry students from New Hampshire and Massachusetts to attend the Frühjahrssymposium, organized by Germany’s JungChemikerForum at the University of Rostock in Rostock, Germany. Like the Gordon Seminar, the Frühjahrssymposium is a student-run conference featuring student talks and posters in chemistry.

“I went to Rostock this year not only to learn about the current research being conducted in Europe, but also because I’m interested in bridging the international gap in the field of Chemistry,” says Nick. “This conference is part of a ‘chemistry exchange’ program that the Northeast Section Younger Chemists Committee (NSYCC) has been involved with for the past ten years. American students like those in our group first travel to Germany for the Frühjahrssymposium, and then students from Germany travel to the United States to attend in an American Chemical Society (ACS) Conference. I think it is an excellent way to share science, form new collaborations, and experience other cultures. I’m really looking forward to showing the German exchange students around Boston when they arrive next year.”

At the upcoming Gordon Conference in Polymer Physics, Nick is presenting his research on the glass transition of polymers. A member of Professor Jane Lipson’s group, Nick creates theoretical models that examine both the glass and liquid transition in these materials. Nick’s research focuses primarily on how molecules act right before the glass transition, and examines how the presence of free volume—“empty space”—affects the transition of these substances.

“It’s easy to understand the glass transition by imagining that you’re in a room filled with people—the annual Graduate Poster Session, for example. Suppose you wish to see a poster on the other side of the Top of the HOP. The people around you make it difficult to move, and it takes a while to make your way across the room,” explains Nick. “There’s going to be some pushing and prodding involved, and this requires energy. But suppose you haven’t slept much over the past few days and don’t have the energy to move through the crowd. When molecules are cooled very quickly, this is exactly what happens: when energy is taken from them, they loose their mobility and are left stuck between other molecules in a fluid. It is this transition from ‘mobile’ to ‘immobile’ that my research examines.”

Used to create synthetic materials including chemical sensors, Styrofoam, and Plexiglas, the polymers that Nick examines are long, string-like molecules that, when cooled, form strong glasses. A number of the polymers researched by the Lipson Group are used to make components for devices that operate in demanding conditions—space ships, for example—so it is important that both the structural properties and transition temperatures of these materials are researched.

“When you think about this geometrically, it makes a lot of sense. The structure of a glass made of chain-like molecules which resemble pearl necklaces, tangled together like spaghetti, will be stronger than a glass made of singular molecules which resemble marbles,” explains Nick. “From a practical standpoint, it is important for scientists to understand the properties of these materials so that when a polymer—like polycarbonate, for instance—is used to build bullet-proof walls, the material remains stable.”

In addition to conducting doctoral research at Dartmouth, Nick also plays the piano, serves as a Departmental Representative on the Graduate Student Council (GSC), and is trying to get a book published that he has been drafting for the past eight years.

“While I’ve studied chemistry throughout my academic career, I’ve always been a big reader. In high school, I started writing a ‘whodunit’ mystery novel, titled View From A Pendulum, which is heavily influenced by the writings of Agatha Christie. The plot focuses on a weekend party that takes place in a mansion perched on a cliff. On the first evening, one of the party guests disappears, and the remainder of the work explores the aftermath. I guess in a lot of ways the plot is like the board game Clue.”

In the future, Nick intends to do a research post doc in Europe and to pursue a career that allows him to continue his research in chemistry.

And yes, Nick also hopes to one day publish his novel.
