Associate Research Scientist (2009-2011)
Consultant for Sirtris Pharmaceuticals (2008-2009)
Post-doctoral Research Fellow (2003-2009)

Researched the biochemical and structural components of AMP-activated protein kinase (AMPK), a major drug discovery advance for diseases such as cancer and diabetes. Investigated SNF1, the AMPK homolog in S. cerevisiae, strengthening knowledge of AMPK function and auto-inhibition mechanisms through biochemical and structural research. Published an article about the investigation in Nature, a well-respected industry journal.

* Orchestrated biochemical and structural analysis of S. cerevisiae AMPK kinase domain, AMPK bateman2 domain, and AMPK heterotrimeric core
* Completed protein oligomerization state analysis by gel filtration, static light scattering, native polyacrylamide gel electrophoresis.
* Performed site-directed mutagenesis.
* Employed thermal shift assay methodologies to characterize protein-ligand interactions.
* Performed crystallization trials using protein reductive methylation and/or surface entropy reduction.
* Design and execution of a gene to structure project including biochemical/biophysical characterization of protein-ligand interactions in support of drug discovery for Sirtris Pharmaceuticals.

HARVARD UNIVERSITY, Boston, Massachusetts * 2002-2003
Post-Doctoral Research Fellow, Joslin Diabetes Center

Constructed expression vectors for proteins linked to metabolic regulation and autoimmune disease. Performed large-scale expression and purification of AIRE proteins and AMPK. Conducted crystallization trials of the AIRE protein.

STONY BROOK UNIVERSITY, Stony Brook, New York * 1996-2002
Ph.D. Student

Explored the biochemical/biophysical characterization and structure determination of Molybdopterin Synthase, an enzyme involved in the biosynthesis of the Molybdenum Cofactor. Discovered a structural similarity between the small subunit of Molybdopterin Synthase and ubiquitin demonstrating the evolutionary antecedence of the Moco biosynthetic pathway to the ubiquitin-dependent protein degradation pathway. Published findings in Nature Structural Biology.

Select Accomplishments:
* Discovered structural distinctions in the human sulfite oxidase b5 domain which promote optimal electron transport from sulite oxidase to cytochrome c after solving the crystal structure of the Cytochrome b5 domain from human sulfite oxidase.
* Characterized protein-ligand interactions using isothermal titration calorimetry assays.
* Studied protein stability using circular dichroism assay.
* Used crystallization and structure determination techniques on Cytochrome b5 domain of human sulfite oxidase and Enoyl-CoA hydratase.
