Keith T. Griffin

Keith Griffin, Ph.D., M.S.

Postdoctoral Fellow

NCI Shady Grove | Room 7E564

Keith T. Griffin, Ph.D., M.S., joined the Radiation Epidemiology Branch (REB) as a predoctoral fellow in June 2017, and was promoted to postdoctoral fellow in August 2022. He earned his M.S. (2016) and Ph.D. (2022) in nuclear and radiological engineering with a minor concentration in medical physics from the Georgia Institute of Technology in Atlanta, Georgia. As part of his core research interests, Dr. Griffin employs Monte Carlo computational simulations to calculate organ absorbed doses associated with environmental and medical external exposures. For his dissertation research, he developed an automated workflow for performing retrospective dosimetry on pediatric patients who underwent passive scattering proton therapy. 

In REB, Dr. Griffin is working under the mentorship of Choonsik Lee, Ph.D., senior investigator and head, Dosimetry Unit, to help establish the computational dosimetry methods needed for future epidemiological studies on the use of radiation in medical procedures, as well as for the atomic bomb survivors at Hiroshima and Nagasaki. In 2024, Dr. Griffin received the DCEG Fellows’ Award for Research Excellence.
