His focus of work has been the use of modern microscopy techniques (light, scanning and transmission electron microscopy) in association with biochemical, molecular and immunological techniques to analyze the structural organization of the protozoa as well as their interaction with host cells. He has been a member of the editorial board of several journals such as Acta Microscopica, BMC Microbiology, Experimental Parasitology, Frontiers in Immunology, Journal of Eukaryotic Microbiology, Micron, Parasitology International, Parasitology Research, among others. He edited several books, including one from the Microbiology Monographs series entitled “Structures and Organelles in Pathogenic Protists”. He has been president of several national and international scientific societies in the areas of Parasitology and Microscopy. He also occupied several administrative positions such as Rector of the North Fluminense State University, State Secretary for Science and Technology of Rio de Janeiro, Vice-Minister of Science and Technology of Brazil, and President of Finep, the main Brazilian agency that supports the establishment of scientific infrastructure in Brazil.
