Dr. Justin Colacino is an Assistant Professor of Environmental Health Sciences in the School of Public Health. His research focuses on understanding environmental and dietary factors in carcinogenesis and cancer prevention. Specifically, the goal of his research is to characterize the environmental susceptibility of normal human stem cell populations, elucidating the etiology of sporadic cancers. Of particular interest are understanding the changes that occur at the epigenetic and transcriptional level, changes which affect not only gene expression but also how progenitor cells differentiate and divide. His research group combines wet lab bench work and bioinformatic and statistical analysis of large scale genomic and epidemiologic data sets to translate findings from in vitro models to the population level. Dr. Colacino is an active member of the Society of Toxicology (SOT) and the American Association for Cancer Research (AACR) and serves on the Editorial Review Board of Environmental Epigenetics and the Editorial Board of Cancer Research.
