Biosketch
I am an ABR certified Medical Physicist in the Maryland Proton Treatment Center and an Assistant Professor at the University of Maryland, Baltimore. I have diverse clinical and academic experiences in both Proton and Linac (photon) radiation therapy, including Monte Carlo radiation dose engine commissioning and modification, LET (linear energy transfer) modeling and simulation, FLASH (ultra-high dose rate radiation) radiotherapy, small animal research platforms, machine QA development and clinical medical physics practice. I also have research experience in Astrophysics including Gamma-ray bursts, MHD simulation and particle acceleration.
Research/Clinical Keywords
Proton radiation therapy; Monte Carlo dose engine; LET (linear energy transfer); FLASH (ultra-high dose rate radiation) radiotherapy; Small animal research platforms (SARRP),
