Dr. Calzo is a developmental psychologist, an Instructor in Pediatrics at the Harvard Medical School, and a Research Scientist in the Division of Adolescent and Young Adult Medicine at Boston Children’s Hospital. He is currently the Co-Chair of the Males & Eating Disorders Special Interest Group of the Academy for Eating Disorders. Dr. Calzo’s research focuses broadly on the development of gender and sexual orientation health disparities in adolescence and young adulthood. Dr. Calzo’s work on body image and eating disorders, funded by the National Institute of Child Health and Human Development and the National Institute on Drug Abuse, focuses on body image and eating disorder risk in heterosexual and sexual minority (i.e., gay, bisexual, mostly heterosexual) males. His work breaks new ground by being among the first to trace the development of leanness and muscularity concerns, physical activity, and product use (e.g., creatine, steroids) in both heterosexual and sexual minority males across adolescence. Dr. Calzo’s current work examines how stress and socialization processes in specific contexts (e.g., sports, engagement in sexual minority community contexts) contribute to sexual orientation disparities in eating disorder risk, and how such factors can be targeted in preventive interventions to promote health in all boys and men. Dr. Calzo also serves as a scientific consultant to the Massachusetts Commission on Lesbian, Gay, Bisexual, and Transgender Youth and is a faculty affiliate of the Women, Gender, and Health Interdisciplinary Concentration at Harvard School of Public Health. He received his PhD from the University of Michigan.
