Profile

My laboratory studies a variety of membrane transport proteins in parasitic protozoa of importance to human health such as Leishmania and the African trypanosomes.  Overall we focus upon the structure, function, and biological activities of transporters that play especially important roles in the ability of the parasite to survive within both its insect vector and its human host.  The research utilizes a multidisciplinary approach combining biochemistry, molecular biology, cell biology, genetics, and pharmacology.  One approach is to clone genes for important transporters, generate null mutants deficient in these transporters, and examine the phenotypes of the mutant parasites.  Another major direction involves examining the structure and function of individual permeases by site-directed mutagenesis followed by transport assays or by electrophysiological characterization of the permease.  We are also interested in the trafficking of different permeases to distinct subcellular locations.
