Research in a broad range of topics in biophysics is carried out by Marcelo Gleiser from the Department of Physics and Astronomy and by Brian Pogue from the Thayer School of Engineering.

Astrobiology is the scientific study of the origin of life and of the possibility that life exists elsewhere in the universe. As such, it's an inherently interdisciplinary field, combining tools from physics, astronomy, biology, and earth sciences. At the Department of Physics and Astronomy, research focuses mostly on questions related to the origin of life on Earth and possibly other planets and moons. In particular, we develop theory and computer models describing how simple chemical reactions that took place in primitive Earth evolved to bridge the gap between nonlife and life. Our research combines techniques from statisical and nonlinear physics with nonequilibrium physical chemistry, informed by findings in astronomy and the earth sciences.

Imaging the proteins that cause the human body to function is exceptionally difficult, and yet being able to image molecular function in diseased tissues such as cancer would fundamentally change the paradigm of how disease is detected and treated in health care. Our research is focused on developing the tools for imaging molecular function in vivo, and combining them with traditional imaging tools such as x-ray, ultrasound and magnetic resonance imaging. Success in this area requires the development of new hardware tools, customized image reconstruction software, and testing the use in pre-clinical and clinical trials. All of these areas are being advanced in our lab, towards realization of this new paradigm of molecular imaging in vivo.
