Dr. OP Hamnvik, an endocrinologist and the Director of the Center for Oncoendocrinology at Brigham and Women's Hospital (BWH), discusses his career to becoming an endocrinologist with Blake Smith (host). Originally from Norway, Dr. Hamnvik takes us around the globe as he began his journey as a medical student in Ireland, followed by residency and fellowship at BWH in Boston. He now runs the endocrinology fellowship at BWH, in addition to educating thousands of students and faculty through his role as the Education Editor at the New England Journal of Medicine (NEJM). Outside of education, he has a particular interest in caring for transgender patients, in addition to seeing cancer patients at the Dana-Farber Cancer Institute whose immune therapy (checkpoint blockade) has resulted in autoimmune endocrinopathies. Dr. Hamnvik closes the episode with a few takeaways for listeners interested in pursuing a career in endocrinology, in addition to some tips for our international student following who might want to pursue future clinical training in the US!
