My laboratory is focused on the control of Chagas disease, a leading cause of heart disease caused by Trypanosoma cruzi, a protozoan parasite. Our current focus is the population genetics of the parasite vector, Triatoma dimidiata, in Central America and Mexico. Much of this work has been done in collaboration with the Laboratory of Applied Entomology and Parasitology (LENAP), headed by Dra. Carlota Monroy at the University of San Carlos in Guatemala. In addition, in 2006 we identified the first locally-acquired human case in Louisiana and are investigating the Chagas transmission cycle in the southern U.S. including T. cruzi infection prevalence in the insect vector (Triatoma sanguisuga), non-human primates, dogs and wild animals and the phylogeny and population structure of U.S. triatomines.
