About Dimitri Dimitroyannis

Dimitri Dimitroyannis received a PhD in experimental nuclear and high-energy physics from the University of Maryland and subsequently pursued postgraduate research at Northwestern University in subatomic nuclear structure and at the Dutch Institute for Nuclear Research in nuclear physics with internal cerium-doped crystals. More than 15 years ago, Dimitri Dimitroyannis shifted focus from experimental nuclear physics and went into medical applications. He currently serves as the chief of medical physics at New York-Presbyterian Hospital, affiliated with Weill Cornell Medical College. There, he concentrates on streamlining medical physics operations and standardizing medical physics services in a busy academic clinical environment. Additionally, he is involved in the planning of a new outpatient radiotherapy clinic, which is presently under construction.

Dimitri Dimitroyannis is the author or coauthor of over 40 articles in peer-reviewed journals on topics such as nuclear radiation detector development, science education, and clinical medical physics. He is a member of the American Physical Society and the American Society for Therapeutic Radiation Oncology, among other professional organizations. Dimitri Dimitroyannis received a MacArthur Foundation grant to study novel radiotherapy modalities, including demonstration of a vertical CT scanner for gantryless radiotherapy, and he has taught at as adjunct faculty in academic institutions including Northwestern University, Harvard Medical School and Texas A&M.
