The Harvard–MIT Program in Health Sciences and Technology, or HST, is one of the oldest and largest biomedical engineering and physician-scientist training programs in the United States. It was founded in 1970 and is the longest-standing collaboration between Harvard University and the Massachusetts Institute of Technology (MIT). Within the program, graduate and medical students are registered with both MIT and Harvard and may work with faculty and affiliated faculty members from both communities. HST is a part of MIT's Institute for Medical Engineering and Science and forms the London Society at Harvard Medical School.
