RESEARCH ADMINISTRATION


I am currently on assignment with the National Science Foundation in the Office of International and Integrative Activities in the Office of the Director.

My NSF contact information is here.

From 2006-2012, I worked for the Vermont State EPSCoR organization to build research and education infrastructure in Vermont. I served as Senior Associate Director of the organization, which has oversight of the EPSCoR and EPSCoR-like programs from the National Science Foundation, National Institutes of Health, Department of Energy and Department of Agriculture.

These duties included serving as Associate Director for Vermont EPSCoR (EPS-0701410, EPS-1101317, EPS-1107945) and the Vermont Genetics Network (GM103449). In addition, I served on the Executive Committee for the Northeast Cyberinfrastructure Consortium (EPS-0918284). My portfolio included evaluation and assessment, private sector initiatives, and cyberinfrastructure initiatives.

In 2012, I accepted a position as a Program Officer in EPSCoR office at the National Science Foundation. (link).

RESEARCH

I received my Sc.B. in Physics from Brown University and my Ph.D. in Physics from the University of Illinois at Urbana-Champaign.  I was a  Director's Postdoctoral Fellow at Los Alamos National Lab working on kinetic crystallography of heme proteins before coming to UVM in 1998.

I am interested in the structural and functional consequences of dynamics of biological molecules.  The projects in my lab are aimed at achieving a quantitative understanding of biological function and enzyme mechanism.  My interests include spectroscopy of proteins and nucleic acids and the use of biomolecules in nanotechnological applications.  I am affiliated with the Center for X-ray Crystallography and the Structural Biology effort at UVM.

Current projects

  • Magnetic circular dichroism on small organic molecules (meso tetra-phenylporphyrin)

  • Protein dynamics of heme proteins (myoglobin, hemoglobin, cytochrome P450cam);
