Aden Evens brings a wide-ranging approach to his research, teaching, and performance in the field of new media studies. His scholarship on the evolving forms of new media and digital technologies is informed by research in philosophy, mathematics, music, computing, and literature. He holds an A.B. from Harvard University and pursued graduate work at McGill University, where he obtained both his M.A. and Ph.D. degrees.

Dissertation research on ethics in the works of French philosopher Gilles Deleuze represents the single greatest influence on Evens's ongoing scholarly production, which follows Deleuze's eclectic and multidisciplinary model. This postmodern theory not only points toward the breadth of subject matters that Evens takes on, but focuses the critical questions that he brings to those subjects, primarily questions about the ways in which technologies generate and alter aesthetic and ethical experience. The principal example of this research is his first book, Sound Ideas: Music, Machines, and Experience (University of Minnesota Press, 2005), which considers the ways in which audio technologies, especially digital audio technologies, shape our interactions with sound and music, as performers, composers, critics, analysts, consumers, and listeners.

Prior to joining the Dartmouth faculty, Evens held teaching positions at The New School in the Department of Cultural Studies; at SUNY-Albany in the Department of English; at Harvard University as a preceptor in expository writing; and at MIT as an assistant professor of technical communication in the Program in Writing and Humanistic Studies. He received a Phineas Sprague Scholarship for Outstanding Achievement in Mathematics and the Sciences from Harvard, both the McGill and the Manulife Fellowships from McGill University, and a Pembroke Postdoctoral Fellowship at Brown University. His initial teaching assignment at Dartmouth includes a class in new media studies, and he is also organizing a symposium at the Leslie Center on new media, to be held this October.

His articles are widely published in scholarly journals, both print and digital. Recent works include “Senseless Violence,” published in Synoptique (2006) and “Object-Oriented Ontology,” in Angelaki (2006). Evens is a frequent speaker at conferences and symposia in the United States and Canada, and has been a guest lecturer at several art museums, including the Baltimore Museum of Art and the School of the Museum of Fine Arts (Boston). He teaches in the areas of the philosophy and culture of technology; aural culture and music, with a specialization in 20th-century experimental and improvisational works; ethics and aesthetics; literature and composition; and studio production and sound design. In addition to his book and articles, Evens has also released two music recordings (CD/LP) on the Constellation label based in Montreal, under the project title, re:.

Matissa Hollister studies poverty, social stratification, the labor market, and organizations. She is a graduate of Haverford College, received a Master of City Planning degree from MIT, and a Ph.D. in Sociology and Social Policy from Harvard University. Her current research focuses on the "New Economy," how recent trends such as globalization, the decline of manufacturing, and the spread of technology have affected labor market opportunities. Her dissertation, "Careers in a Changing Economy: Occupations and Intergenerational Mobility Among Two Cohorts of the National Longitudinal Surveys," examines how these economic changes have affected the interplay between socioeconomic background and career trajectories. Hollister is also the author of "Does Firm Size Matter Anymore? The New Economy and the Causes of the Firm Size Wage Effect," which was published in the American Sociological Review.

Hollister brings her expertise in these areas to the classroom, where she is teaching courses on the sociology of work; the quantitative analysis of social data; food and society; and poverty, the new economy, and employment policy. Before coming to Dartmouth she held teaching posts at Harvard as a teaching fellow and, later, as an instructor. She has also taught at the Community College of Vermont.

Hollister earned several distinctions at Harvard, including the Dean's Award for Excellence in Student Teaching and the Taubman Center Urban Award for Papers on the Implementation and Management of Programs to Serve the Poor. This past year she was a Rockefeller Postdoctoral Fellow at Dartmouth and she spent the summer in California at the Center for the Advanced Study in the Behavioral Sciences.

James Henry Scott's research investigates the phenomena that connect biology and geochemical processes. He believes that there is a synergism between microbial life and the planet that can be observed and measured, and utilizes a range of approaches to examine how the Earth's smallest inhabitants can affect it on a geochemical scale. The approaches used can range from detecting minute isotopic changes associated with biology to more traditional microbiological and molecular approaches. Conversely, he is intrigued by how the geochemistry of the planet can lead to adaptations and ultimately evolutionary changes in microbial communities. His research interests range from eutectic geobiochemistry—testing the ability of microbes to adapt and survive in high-pressure eutectic ices—to investigation of ancient environments and how ancient metabolic pathways were shaped by the earth's prebiotic chemistry.

Scott received both his B.S. and Ph.D. degrees from the University of Wisconsin-Milwaukee and he has studied at the National Institutes of Health and at the Marine Biological Laboratory in Woods Hole, Mass.

From 1997 to 1999 he conducted research at the NASA/Caltech Jet Propulsion Laboratory and, in 1999, became a Postdoctoral NSF Associate at the Carnegie Institution of Washington's Geophysical Laboratory, where he held the post of associate staff scientist before coming to Dartmouth. He is the recipient of numerous awards and honors, including a NASA Astrobiology Institute Postdoctoral Fellowship, a Carnegie Institution Postdoctoral Fellowship, and a membership on the National Academy of Science's NRC-Space Studies Board Task Group on "The Limits of Organic Life in Planetary Systems and the Committee on the Origin and Evolution of Life." He is a collaborator and coinvestigator for the Mars Science Laboratory, and the equipment designed by his team will conduct measurements of that planet’s surface to evaluate the potential for life on Mars during a mission scheduled to be launched in 2009.

He is the author of numerous articles that have appeared in such journals as Science, Applied and Environmental Microbiology, Nature Biotechnology, and the Journal of Bacteriology, and he is a frequent speaker at seminars sponsored by a range of institutions and organizations focused on the study of life in extreme environments.

Petia Vlahovska is interested in understanding how the microstructure of complex fluids determines their behaviors, in particular their flow properties. Blood, paints, shampoo, and foods such as mayonnaise and ice cream are a few examples of complex fluids, which are dispersions of micron-sized particles or drops. The fundamental importance and broad practical applications of these substances make their study both significant and highly interdisciplinary, involving engineering, physics, chemistry, and applied mathematics.

Vlahovska comes to Dartmouth from Brown University where she was a visiting assistant professor in the Division of Engineering. She holds two M.Sc. degrees, both from the University of Sofia in Bulgaria, and she received her Ph.D. from Yale University. Fluent in four languages, she has made presentations at seminars and professional gatherings across the United States and around the world.

Vlahovska's articles have been published in scholarly journals and she has held two fellowships, one at the Max-Planck Institute of Colloids and Interfaces in Germany, where she worked in the Membrane Biophysics group, and another at Cambridge University in England, where she received the David Crighton fellowship to facilitate her work with the Biological Mechanics Group at the Department of Applied Mathematics and Theoretical Physics. Her teaching and her research have consistently been recognized with awards, including the Department of Chemistry scholarship for outstanding student at the University of Sofia, the Evrika Foundation scholarship for excellence in natural sciences, and the Prize Teaching Fellowship from Yale University, for outstanding performance and promise as a teacher.

Vlahovska's current research focuses on the rheology of surfactant-laden emulsions, the dynamics of artificial cells in flow, and the flow of suspensions of swimming microorganisms.

Vlahovska is a member of the American Physical Society (APS) and was session chair for American Chemical Society (ACS) symposia in 2004 and 2005.

Afra Zomorodian
Assistant Professor of Computer Science

Afra Zomorodian's research focus is within the emerging area of computational topology. Topology is the area of mathematics concerned with how a particular space is connected. The space could be real, such as the surface of donut, or abstract, such as the conformation space of a protein: a high-dimensional space that contains all possible positions of the atoms of a protein as it folds into its native state. Topology gives stable measures for capturing global qualitative features of these spaces, such as whether a shape has a tunnel, like a donut, or encloses empty space, like a soccer ball. Computational topology brings the theory of algebraic topology into computer science for solving real-world problems.

Zomorodian's work may be divided into theory and practice. On the theory side, he has worked extensively on persistent homology, a concept he introduced in his dissertation. This theory allows for the recovery of the topology of a shape from a set of noisy samples. On the practice side, he has implemented all his algorithms and incorporated some of them into free algorithm libraries and free software, such as the Computational Geometry Algorithms Library (CGAL) and PLEX, a library of Matlab routines for computation using simplicial complexes. He has also applied his research to solving problems in diverse fields. Recent examples include analyzing massive molecular dynamics simulations of phospholipid bilayer fusion (biophysics), understanding the local structure of natural images (image processing), and identifying colon polyps using discrete differential geometry (radiology).

Zomorodian received his B.S. from Stanford University and his Ph.D. from the University of Illinois at Urbana-Champaign, both in computer science. He was then a postdoctoral fellow at Stanford and a researcher at the Max-Planck-Institut für Informatik (MPII) in Saarbrücken, Germany. During the fall quarter, he is a research professor at the Mathematical Sciences Research Institute (MSRI) in Berkeley, where he is a resident in the Computational Applications of Algebraic Topology program. Zomorodian has taught extensively in the past, received a teaching award at Illinois, organized courses at Stanford and MPII, and published a monograph titled Topology for Computing through Cambridge University Press. His work is currently supported by Defense Advanced Research Projects Agency (DARPA) through a grant in the Topological Data Analysis (TDA) and NeoVision  programs.
