Introduction

Interested in a research position in my lab this summer? Click here to make an appointment to talk to me about that.

My research interests are in the broad areas of protein-RNA interactions and RNA structure. These areas lie at the intersection of biology and chemistry, and encompass wide variety of scientific perspectives. These range from the "biological" questions of which proteins interact with particular RNAs, what the consequences of these interactions are to the living cell, and how particular interactions evolved, to the more "chemical" questions of how a specific functional group influences a macromolecular interaction or changes the structure of a macromolecule, and how a simple chemical reagent can be used to elucidate biological function.

For several years research in the lab has been focused on characterizing substrate recognition of alanyl-tRNA synthetases which aminoacylate the highly unusual tRNAs found in animal mitochondria. New projects involve evaluating aminoacyl-tRNA synthetases from parasitic worms as potential drug targets.

Education & Professional History

Oberlin College, BA; Columbia University, MA, PhD.; Post-doctoral work at M.I.T. and the Scripps Research Institute
