previous research
Assistant Scientist with Prof. Martin T. Zanni
Department of Chemistry, University of Wisconsin - Madison

Most recent research included the study of the misfolding and aggregation of human islet amyloid polypeptide (amylin), processes thought to lead to type 2 diabetes, using isotope labeling and two-dimensional infrared spectroscopy.

past research

Research with Prof. Bern Kohler, at Ohio State University (now at Montana State University), involved the time-resolved study of the photophysics of DNA bases and polymers; ground-state vibrational cooling and excited-state dynamics using femtosecond transient absorption in the UV, visible and mid-IR.

Research with Prof. Bruce S. Hudson, at Syracuse University, involved the study of the vibrational properties of organic moleucles through inelastic neutron scattering spectroscopy and computational methods.

Research with Prof. Shaul Mukamel, at the University of Rochester (now at the University of California, Irvine), involved theoretical study of excitonic coupling in light harvesting complexes using the Collective Electronic Oscillators approach.
