BA, Biology and Environmental Sciences, Columbia University, New York, U.S., 1997

PhD, Environmental Health Sciences, Columbia University, New York, U.S., 2010


My main research focus involves quantitatively modeling and preventing radiation-induced carcinogenesis. My other interests include understanding and modeling other biological effects of ionizing radiation, including 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.
