I am a Medical Physicist in the Maryland Proton Treatment Center and an Assistant Professor at the University of Maryland, Baltimore. I have diverse clinical and research interests in both Proton and Linac (photon) radiation therapy. The clinical expertise focuses on external beam therapy, SRS/SBRT, proton therapy, brachytherapy, radiopharmaceutical, and online adaptive radiation therapy. Currently, I have multiple interests in medical physics research including proton therapy, FLASH, MRI-guided radiation therapy, ultra-low-field MRI system development and implementation.
