My main research focus involves quantitatively modeling radiation effects including radiation carcinogenesis, normal tissue complications, radioresistance and non-targeted effects. My previous training and experience have been interdisciplinary, starting with biology (BA from Columbia University) and medicine (MD from SUNY Downstate College of Medicine). I completed the intensive Cancer Training Program (Columbia University, Mailman School of Public Health), where for three years I improved my skills in cancer epidemiology and biostatistics. I received a PhD degree with distinction in 2010 from the department of Environmental Health Sciences (Columbia University, Mailman School of Public Health) for mechanistic mathematical modeling of radiation-induced carcinogenesis. My work in this field, and also in the field of resistance to ionizing radiation, has resulted in multiple peer-reviewed publications.
