Research Abstract

My work integrates research, clinical service, and teaching in Radiation Oncology, with recent focus on Cancer Nanomedicine: developing novel nanoparticle-aided radiotherapy (NRT) treatment modalities. I lead a research group currently focused on the development of 3 novel NRT approaches to enhance radiotherapy for prostate cancer, lung cancer and retinal diseases, without increase in normal tissue toxicity. I am also co-director of Global Health Catalyst: a transformative initiative employing advanced information and communication technologies (ICTs) to catalyze high impact international collaborations in Radiation Oncology, cancer prevention and advocacy towards elimination of global cancer disparities.
