Medical Physics Resident

Indiana University School of Medicine

I am the Chief Medical Physics Resident in the Department of Radiation Oncology at Indiana University, where I focus on the clinical aspects of cancer treatment through radiation. My research interests include radiation physics, radiopharmaceutical therapy, and Monte Carlo simulations. I specialize in applying Monte Carlo simulations to address challenges in radiation physics, encompassing dosimetry and radiation biology. A key feature of my research is close collaborations with experts in radiopharmaceutical dosimetry, molecular imaging, and radiation transport simulations.

My doctoral thesis explored dosimetry in radiopharmaceutical therapy and quantitative imaging in nuclear medicine. Specifically, I investigated into two main areas: (1) dosimetry of β- and α-emitting radionuclides, and (2) Monte Carlo simulation of PET scanners, complemented by rigorous validation.

Short Bio:

I hail from Nareshwor, Gorkha, Nepal, where I cherished my formative years. I earned my B.Sc. (2008) and M.Sc. (2012) degrees from Tribhuvan University. I then pursued my second master’s degree at the University of South Dakota in 2017 and completed my Ph.D. in physics at the University of Iowa in 2022.

Outside of my professional life, I find joy in cycling and appreciate the tranquility of nature. My literary interests include both fiction and non-fiction, and I also enjoy various gaming activities, such as Carrom, card games, and exploring culinary arts.
