Dr. Lopez is an Assistant Professor of Epidemiology in the Department of Preventive Medicine and Population Health (PMPH). He is a cancer epidemiologist with a research focus on cancer health disparities (risk, progression and survivorship of prostate cancer and hormone- and obesity-related cancers) and men’s health research (endogenous and exogenous testosterone, erectile dysfunction and lower urinary tract symptoms). He also studies the role of modifiable factors that influence the risk, progression and survivorship of prostate, hormone- and obesity-related cancers, such as obesity, metabolic syndrome and dietary patterns. A key interest in the research program of Dr. Lopez is to determine the role of race and ethnicity in the interplay between endogenous and exogenous testosterone, obesity, dietary patterns and the risk, progression and survivorship of prostate cancer, hormone- and obesity related cancers. He is an active member of the Society for Epidemiologic Research (SEC), American Association for Cancer Research (AACR) and American Urological Association (AUA).
