My work addresses some of the major challenges in parasitic diseases, by combining basic biological approaches to investigate disease determinants with applications for vaccine and drug development. My early research focused on the identification of determinants of visceral leishmaniasis by comparing cutaneous and visceral Leishmania laboratory strains and clinical isolates. I am now studying the factors that mediate Trypanosoma cruzi organ tropism and progression from asymptomatic infection to chronic Chagas cardiomyopathy. In addition, I am part of our lab's efforts to identify and develop compounds active against leishmaniasis, Chagas disease, and sleeping sickness by high throughput screening.
