The Wilmot lab focuses on the biosynthesis of protein and peptide-derived enzyme cofactors. She employs X-ray crystallography, UV-vis absorbance spectroscopy in the crystal, and mass spectrometry. She freeze-traps catalytic intermediates in the crystal, leading to "snapshots" along the reaction pathway. These are then assembled into a "movie of catalysis" at the molecular level

David Zarkower, PhD, Professor, Dept of Genetics, Cell Biology & Development
Disorders of sexual differentiation are among the most common congenital syndromes and often have serious medical and social consequences. Research in the Zarkower laboratory aims to uncover the molecular and genetic mechanisms that underlie sexual development.  To accomplish this goal, they study model organisms (C. elegans; mouse) in which powerful genetic, genomic, and molecular approaches are possible.
