Research Summary

My research group is engaged at the interface of chemistry and biology. As medicinal chemists, we design and synthesize small molecules that modulate disease pathology at the level of the enzyme, cell, and whole animal, with active projects in cancer, infectious disease, and neurodegeneration. Our group also developed a parallel synthetic methodology to produce a library of disulfide 'fragments', thereby enabling cysteine-disulfide (Tethering) screening at UCSF. Finally, we design, synthesize and validate novel small molecule probes for the study of labile ferrous iron in biology and disease. Most recently, we described the first of a new class of activity-based probes for proximity labelling of proteins in an iron-dependent fashion, thus enabling the first chemoproteomic studies of the labile iron 'interactome'.
