Dr. Shaheen A. Dewji is an Assistant Professor in the Department of Nuclear Engineering at Texas A&M University and a NSSPI Faculty Fellow. Dr. Dewji completed her Masters and Ph.D. degrees in Nuclear and Radiological Engineering at the Georgia Institute of Technology in Atlanta, GA. She received her Bachelor of Science in Physics from the University of British Columbia in Vancouver, Canada. Having established the Radiological Engineering, Detection, and Dosimetry (RED2) Laboratory at Texas A&M University, Dewji’s research group has focused on harnessing both computational capabilities in radiation transport modeling and experimental measurements using radiation detection for applications in radiation protection, dosimetry, health physics, and nuclear materials accounting. Her research thrust in computational dosimetry investigates the development of dose coefficients using age/sex-specific anthropomorphic computational phantoms and radionuclide biokinetic models for occupational nuclear workers, members of the public, nuclear medicine, space, defense, and emergency response. Research activities in radiation detection employ validation and verification of gamma-ray spectroscopic detector responses for contaminated environmental media; field triage assessment of radiation uptake during nuclear, radiological, and fission product release events; and nuclear materials control, accounting, and safeguards of special nuclear material. In her prior role as a Radiological R&D Staff Scientist in the Center for Radiation Protection Knowledge at Oak Ridge National Laboratory, her work included assessment of patient release criteria for iodine-131 patients for the U.S. Nuclear Regulatory Commission, as well as updates to the U.S. Environmental Protection Agency’s Federal Guidance Report (FGR) 12 on external exposure to radionuclides in environmental media and FGR 13 on dose coefficients and radiation risk associated with the inhalation and ingestion of radionuclides. Prior, Dr. Dewji spent five productive years with the Safeguards and Security Technology Group at ORNL as a Nondestructive Assay Systems Engineer, where she employed gamma-ray methods for nuclear material control and accountancy for front and back ends of the fuel cycle through verification and validation experiments in the Safeguards Laboratory on enrichment, holdup (MUF), and signature analysis. Dewji is an active member in both the American Nuclear Society (ANS) and Health Physics Society (HPS). In the ANS, she serves as Chair of the Radiation Protection and Shielding Division and Outgoing Chair of the Nuclear Nonproliferation Policy Division (2018-2019). In the HPS, she is Board Liaison of the Homeland Security Section, member of the Government Relations Committee, member of the HPS President’s Special Task Force on Radiation Protection Needs, and recipient of the esteemed 2018 Health Physics Society Elda E. Anderson Award.
