Dr. Juan Guillermo Perez is a Colombian physician, epidemiologist, and bioethicist. During his 13-year career, he contributed to the design and conduct of medical research in a Latin-American-recognized Cardiovascular Hospital. In particular, he was involved in multi-centric clinical trials funded by the Ministry of Health and the Pharmaceutical Industry, as well as collaborative cardiovascular research integrating different LATAM countries. He helped with the development of National Clinical Guidelines for different topics as a research synthesis specialist (for the management of people living with COVID-19, HIV, Hypertension, and Asthma). As an epidemiologist, he integrates bioethical reflections into research projects. This vision helped him to contribute to the creation of the Institutional IRB at the Universidad del Rosario and the Latin-American Network for Research Integrity (RIIC). Working for the pharmaceutical industry complemented his research training before starting the doctoral program in epidemiology in the United States, as it gave him a broader picture of the research efforts required to understand health priorities, using implementation and translational sciences.
