Teaching Interests

Professor Dewji’s teaching interests focus on core instruction in nuclear engineering and medical physics, with emphasis on radiation protection, dosimetry, radiation detection, shielding, and applied regulatory context at undergraduate and graduate levels. Her courses emphasize mastery of fundamental radiation quantities, particle interactions, radiation health effects, instrumentation, and shielding analysis, reinforced through structured problem solving, computational exercises, and case-based applications drawn from medicine, nuclear energy, and security. Instruction integrates modern computational tools as learning aids within clearly defined academic integrity boundaries, and employs project-based assessments such as dose reconstruction, intercomparison exercises, and applied modeling to support conceptual understanding and professional readiness.

Research Interests

Professor Dewji’s research interests focus on radiation protection, detection, and dosimetry across nuclear engineering, medical physics, and nuclear security applications. Her work emphasizes quantitative modeling of radiation transport, internal and external dose assessment, gamma-ray and neutron detection, radiation shielding, and dose-informed frameworks supporting nuclear security, nonproliferation, and advanced reactor licensing. Research activities integrate multiphysics simulation, Monte Carlo radiation transport, biokinetic modeling, and artificial intelligence to address dose estimation, uncertainty propagation, and consequence assessment in complex exposure scenarios spanning nuclear energy systems, medical applications, environmental monitoring, and emergency response.
