My laboratory uses methods in molecular and structural biology (X-ray crystallography, Cryo-electron microscopy, and Nuclear Magnetic Resonance) to characterize the protein synthesis machinery of parasites, such as the ones causing Leishmaniasis and Malaria, that significantly burden public health. Our long-term goal is to harness this information to develop safe and effective antiparasitic drugs.
