About the Editors


Like the other Nature titles, Nature Medicine has no external editorial board. Instead, all editorial decisions are made by a dedicated team of professional editors, with relevant research and editorial backgrounds.

Chief Editor: João Monteiro

 João received his medical training at the Federal University in Rio de Janeiro, Brazil,  where he also earned a PhD degree, studying mechanisms of tolerance to self-antigens in autoimmune diseases. In 2009, he was named a Pew Latin American Fellow in the Biomedical Sciences, moving to the United States to pursue studies on T cell antigen recognition and in vivo dynamics of the immune responses with Ron Germain, at the National Institutes of Health. João was the senior editor for immunology and translational medicine at Cell from 2013-2017 and in December, 2017, he was appointed Chief Editor of Nature Medicine, where he leads a team of editors and journalists covering news, opinion and research across the entire landscape of translational and clinical research. He has given talks about medicine, science and publishing in many international conferences, and has championed efforts to raise ethical standards and transparency in the reporting of translational and clinical research. João cares about supporting young investigators, creating opportunities to make scientific publishing more inclusive, and harnessing the potential of scientific research to reduce health inequalities globally. Since 2021, he has served as a member of the International Committee of Medical Journal Editors (ICMJE). João is based in New York and you can follow him on Twitter @JMinImmunoland.
