It is with great sadness that we announce Biochemistry Professor Emeritus John Suttie died on December 21, 2020 in Arizona, where he had been living for the past several years. John was a faculty member in Biochemistry from 1961-2001 and a member of the National Academy of Sciences. He was known scientifically for his outstanding work on blood clotting including the metabolism and mode of action of vitamin K; he was also a great mentor and dedicated teacher. We will miss him dearly. A full written tribute from the Biochemistry community will be shared on our website in the coming days.
