Description of Research Expertise
My laboratory is attempting to better understand the molecular physiology of human blood flukes such as Schistosoma mansoni. Schistosomes are parasitic flatworms that cause schistosomiasis. Approximately one sixth of the world's population is at risk for this disease, and hundreds of millions of people worldwide are infected with these parasites. The lab focuses on four major projects: the physiology of a schistosome TRP channels, ion channels involved in sensory functions; the role of schistosome multidrug resistance proteins in parasite physiology, and the interaction of these transporters with praziquantel, the drug of choice against schistosomiasis; the structure and function of schistosome voltage-gated Ca2+ (Cav) channels, and their role in praziquantel action; and development of point-of-contact molecular diagnostic tools. The methods we use include molecular biology, RNA interference, electrophysiology, heterologous expression, behavioral assays, and calcium imaging, among others.
