Biography
Dr. Mollie Barnard is a molecular and genetic epidemiologist whose research focuses on the etiology of breast and ovarian cancers and the elimination of racial disparities in cancer outcomes. She leverages large, diverse epidemiologic cohorts linked with molecular data to identify modifiable risk factors and biologic pathways that can be translated into prevention and survivorship strategies.
Dr. Barnard is Principal Investigator of an American Cancer Society Research Scholar Grant investigating how cardiometabolic health influences breast cancer risk, tumor biology, and immune profiles among Black women. By combining prospective cohort data with tumor gene expression and immune infiltration analyses, this work seeks to uncover mechanisms driving aggressive disease and to identify opportunities for targeted screening, prevention, and treatment.
Her prior research has examined the role of inflammation in ovarian carcinogenesis. Findings from her work on anti-inflammatory drug use and ovarian cancer risk indicated that the inverse association between aspirin use and ovarian cancer risk may be specific to low-dose aspirin. In related work, she demonstrated that women with deep infiltrating endometriosis and/or ovarian endometriomas have a substantially greater risk of ovarian cancer compared to those with less severe endometriosis subtypes.
Dr. Barnard is dedicated to training the next generation of scientists. She has mentored master’s students, PhD students, and medical students in cancer epidemiology, study design, and data analysis. She has a longstanding commitment to supporting students from underrepresented backgrounds, serving as a faculty mentor for the Society for Epidemiologic Research’s LGBTQIA+ mentoring group, mentoring students through the Dana-Farber Continuing Umbrella of Research Experiences (CURE) Program, and volunteering as a program leader for Minds Matter Boston.
