Ernesto T. A. Marques Jr. graduated “summa cum laude “ as a medical doctor in 1993 at the “Universidade Federal de Pernambuco” in Brazil. In 1999 Dr. Marques obtained a Ph.D. degree in Pharmacology and Molecular Sciences at The Johns Hopkins University School of Medicine. In 2003 Dr. Marques became a consultant for the Fundação Osvaldo Cruz of Brazil. In 2006 Dr. Marques was appointed as Assistant Public Health Researcher at the Fundação Osvaldo Cruz, Centro de Pesquisa Aggeu Magalhães - CPqAM and founded of the Virology department known as LaViTE. In 2009 Ernesto joined the Center for Vaccine Research as Associate Professor in the Department of Infectious Diseases and Microbiology at the University of Pittsburgh Graduate School of Public Health. In 2011 University of Pittsburgh and Fundação Osvaldo Cruz established a collaborative agreement and Dr. Marques has assumed the role of the liaison between the two institutions. Currently, Dr. Marques divides his time between Recife, Brazil and Pittsburgh and devotes his work to translational research on the development of preventive and therapeutic immunotherapies and diagnostic tools for epidemiological research. Dr. Marques research interests are focused on infectious diseases of importance to global, such as HIV, Zika, dengue and yellow fever.

The research expertise of Dr. Marques is the engineering design of novel vaccines, immunotherapies and diagnostic markers based on defined correlates of protection and/or pathogenesis identified in human samples from well characterized cohorts. The strategy he used is based on de development of detailed T and B cell epitopes maps and characterization of innate immune response (immunomes) induced by the pathogenic agents. The laboratory apply a combination of computational technologies, high throughput immune assays in human samples. Using the immunome maps, we explore patterns correlated either with immunity or pathogenicity and design novel antigen formulations containing selected epitopes , adequate delivery methods and innate immune stimulation. Currently we are applying this strategy to study Dengue, yellow fever, HIV among other agents.
