First person – José Britto-Júnior

First Person is a series of interviews with the first authors of a selection of papers published in Biology Open, helping early-career researchers promote themselves alongside their papers. José Britto-Júnior is first author on ‘The basal release of endothelium-derived catecholamines regulates the contractions of Chelonoidis carbonaria aorta caused by electrical-field stimulation’, published in BiO. José conducted the research described in this article while a master's student in Professor Matheus L. Rocha's laboratory at Faculty of Pharmacy, University of Goias, and is now a PhD student in the Department of Pharmacology at the University of Campinas, Brasil, investigating basic cardiovascular pharmacology, endothelium, endothelial catecholamines and comparative physiology.
