Roheeni Saxena is a Ph.D. candidate on the Toxicology Track in Columbia University’s Department of Environmental Health Sciences. She previously earned a B.A. from Wellesley College, an M.P.H. from Columbia University’s Department of Sociomedical Sciences, and a CPH certification from the National Board of Public Health Examiners. After her undergraduate work, Saxena trained at the National Institute of Mental Health’s Laboratory of Behavioral Neuroscience under Dr. Jacqueline Crawley, and at Harvard’s Behavioral Genetics Laboratory. Prior to beginning her doctoral studies, Saxena served as Associate Director of Educational Programs at Columbia’s Mailman School of Public Health where she contributed to the design and implementation of its novel integrated M.P.H. program. Currently, she works under Dr. Mary Gamble with a research focus on the effects of nutritional deficiencies and arsenic exposures on cognitive outcomes in children and adolescents.
