We are teachers of the laboratory of Parasitology and Immunology of the USP-CEU. What do we have in common?. When we were children, we receive as a gift a microscope, and the game became our passion and, over time, our profession. We work with opportunistic parasites to better understand their distribution, trigger other diseases in man, and improve their diagnosis. We like the history of science, which has led us to have a small museum in our office with instruments and scientific books that represent the advancement of science throughout the years.
