Ehsan Golkar, PhD
2025
Ehsan Golkar received his Ph.D. in 2017 from the National University of Malaysia's Faculty of Electrical and Electronic Engineering. His doctoral research focused on respiratory motion estimation from 4D MRI in External Beam Radiation Therapy . In 2023, he began his career in medical physics as a Research Associate in the Department of Radiation Oncology at Thomas Jefferson University. He later became CAMPEP-certified after graduating from Rutgers University in 2025. His research interests are centered on leveraging medical image analysis and machine learning to advance the field of radiation therapy.
Amrit Kaphle, PhD
2025
Amrit Kaphle earned his PhD in Physics from the University of Tulsa, Oklahoma, in 2019, specializing in nanomaterials and spectroscopy. His doctoral research focused on the synthesis and characterization of nanoparticles, quantum dots, and nanorods using advanced optical and electrical techniques. In 2020, he gained clinical experience as a Quality Assurance Specialist at West Cancer Center in Germantown, TN, where he contributed to a wide range of clinical physics operations. In 2022, Dr. Kaphle began postdoctoral training at MD Anderson Cancer Center in Houston, TX, where his research has encompassed Monte Carlo simulations of gold nanoparticle-mediated radiosensitization, Geant4-based DNA damage modeling, and the development of deep learning frameworks for X-ray fluorescence signal extraction and image reconstruction. In parallel, he completed his CAMPEP Certificate in Medical Physics in 2025 through the Graduate School of Biomedical Sciences at MD Anderson Cancer Center. His current research interests focus on integrating Monte Carlo simulations with radiobiological outcome modeling, with the long-term goal of advancing adaptive and precision radiation therapy.
Hajar Moramand, PhD
2026
Hajar Moradmand, PhD, is a Medical Physics Resident in the Department of Radiation Medicine at MedStar Georgetown University Hospital. She earned her PhD in Medical Radiation Engineering and completed postdoctoral research in the Department of Radiation Oncology at the University of Maryland School of Medicine. Her research focuses on the application of artificial intelligence, radiomics, quantitative imaging to radiation oncology, and understanding biological responses to FLASH proton radiotherapy. She is particularly interested in translating advanced computational methods into clinically meaningful tools to improve treatment personalization, efficiency, and patient outcomes in radiation therapy.
