Core Faculty


  • Distinguished Professor of Health Sciences and Technology and of Electrical Engineering and Computer Science, Massachusetts Institute of Technology
  • Assistant Professor of Medicine, Harvard Medical School


Dr. Mark is Distinguished Professor of Health Sciences and Technology of Electrical Engineering and Computer Science at MIT. He trained in internal medicine at the Harvard Medical Unit at Boston City Hospital and then spent two years in the Medical Corps of the USAF studying the biological effects of laser radiation. He joined the faculty of the EE Department at MIT in 1969 and also the faculty of the Department of Medicine at Harvard Medical School. He has been active in teaching quantitative physiology to undergraduate and graduate engineering students at MIT, and Introduction to Clinical Medicine to HST MEMP students. Dr. Mark is a fellow of the IEEE, a fellow of the American College of Cardiology, and a founding fellow of the American Institute of Medical and Biological Engineering.


  • PhD in Electrical Engineering, Massachusetts Institute of Technology, 1966
  • MD, Harvard Medical School, 1965
  • SB in Electrical Engineering, Massachusetts Institute of Technology, 1960

selected awards/societies

  • Association for the Advancement of Medical Instrumentation 2016 Laufman-Greatbatch Award
  • Fellow, Institute of Electrical and Electronics Engineers (IEEE)
  • Fellow, American College of Cardiology
  • Fellow, American Institute of Medical and Biological Engineering


Dr. Mark’s research activities focus on physiological signal processing and database development, cardiovascular modeling, and critical care decision support and predictive modeling. His group launched the NIH-supported “PhysioNet” (Research Resource for Complex Physiologic Signals) in 1999 to provide open access to major collections of well-characterized physiologic signals and associated signal processing software. His group and others have continued to add data collections to PhysioNet, and it has been the basis of thousands of research publications worldwide. His NIH-funded project, entitled “Critical Care Informatics,” is focused on transforming massive archives of critical care clinical data into new knowledge that will improve the efficiency, accuracy, and timeliness of clinical decision making in intensive care. That project has developed a large new publicly accessible ICU database (MIMIC) containing high resolution clinical data from ~60,000 ICU admissions. It has been added to the archives of PhysioNet and currently has more than 5,000 credentialed users worldwide. Dr. Mark’s own research has depended critically on access to physiologic and clinical data, and he is firmly committed to the importance of making such data freely available to the research community.
