Brief Biography:

Following a three-year post-doctoral fellowship at the Gerontology Research Center, NIA, NIH, under Dr. Pat J. Morin’s advising, I’ve returned to my home country Brazil, where I hold a tenure Associate Professor and Investigator position at the Federal University of Espirito Santo (UFES). I have been engaged in an independent scientific career, being the mentor, thereafter the PI, of many research projects, focusing in the elucidation of the molecular basis of ovarian, breast (especially triple-negative breast cancer), lung cancers, as well as leukemia, and in the discovery of novel strategies to treat the diseases. With this respect, my laboratory is currently investigating the antineoplastic effect of novel synthetic drugs, as well as developing monoclonal antibodies against specific targets identified through genomic and proteomic approaches.
