Radiation Epidemiology Branch: Spotlight on Tenure-Track Investigators

Choonsik Lee

Choonsik Lee Dr. Lee received his master's in Health Physics in 1997 and doctorate in Health Physics in 2002 from Hanyang University in South Korea, where he was extensively trained in computational human phantom development as well as in advanced dosimetry applications. He subsequently joined the Innovative Technology Center for Radiation Safety as a Post-Doctoral Fellow. While in the post-doctoral period, he was actively involved in national research projects investigating computational dosimetry of the Korean population. After the 2 years of post-doctoral study, he went to the University of Florida as post-doctoral researcher where he received extensive training in computational medical physics. Throughout both his doctoral studies and post-doctoral training, Dr. Lee has made considerable contributions to the development of anthropomorphic phantoms and to the improvement of the dosimetry calculations for a variety of radiation applications ranging from radiation protection to medical exposures. Dr. Lee was appointed as a tenure-track investigator in REB in 2009. Dr. Lee is a Corresponding Member of the DOCAL Task Group of the International Commission on Radiological Protection (ICRP).

Lindsay Morton

Lindsay Morton In 2004, Dr. Morton received her doctorate in Epidemiology from Yale University, with a focus on cancer epidemiology. She subsequently joined the Hormonal and Reproductive Epidemiology Branch in DCEG as a post-doctoral fellow and became a research fellow in 2005. During her doctoral and postdoctoral training, she concentrated her research on the etiology of lymphoid neoplasms and expanded her training in molecular epidemiology.

Dr. Morton joined the Radiation Epidemiology Branch in 2008 as a tenure-track investigator, where she continues to research the etiology of lymphoid neoplasms, focusing on identifying the molecular subtypes of lymphoma with prognostic and etiologic significance, and evaluating etiologic heterogeneity among lymphoma subtypes. In addition, she is studying multiple primary cancers, including investigating carcinogenic effects from radiotherapy and chemotherapy, as well as other environmental and genetic risk factors for second cancers. As part of this research, Dr. Morton serves as the principal investigator of an international, multi-center study of second gastrointestinal cancers.
