The microscopic world always fascinated me! To pursue this fascination as a career, I graduated in Biological Sciences (BA/Licentiate degree) in Federal University of Rio de Janeiro, and completed MSc and PhD in Oswaldo Cruz Foundation (FIOCRUZ), Rio de Janeiro, Brazil. I completed a postdoctoral training in the Center for Discovery and Innovation in Parasitic Diseases (CDIPD). In the Dr. Podust laboratory, I am now involved in rational drug development for treatment of Chagas disease and primary amebic encephalitis (PAM) targeting ergosterol biosynthesis enzymes in Trypanosoma cruzi and Naegleria fowleri. Additionally, in collaboration with other researchers in CDIPD, I work on drug discovery/development against a variety of drug targets in T. cruzi. Another area of my expertise is T. cruzi-host cell interactions. The emphasis are on understanding the mechanisms of regulation of extracellular matrix expression during T. cruzi infection to advance treatment of heart fibrosis, a serious condition that affects chronic Chagas' disease patients.
