Faculty Research Interests

Dr. Bloom is a Professor in the Department of Global and Community Health at George Mason University. Bloom’s research focuses on the intersection of environmental pollutants and human health in the U.S. and abroad.

Helen Chin is an Assistant Professor in the Department of Global and Community Health. Her research interests are centered around investigating factors that adversely affect the reproductive health of women and girls, as well as their offspring. Her current focus is studying how endocrine disrupting exposures affect ovarian development and function. 

Dr. Carolyn Drews-Botsch is Professor in the Department of Global and Community Health. Her research has focused on the epidemiology of pediatric conditions and the factors, particularly in the perinatal period, that contribute to their etiology.  Specifically, her work seeks to understand these conditions, and carefully apply modern epidemiologic methods to studies of these conditions. Her research program has included work in a variety of related fields including congenital cataracts, fetal growth restriction – particularly in relationship to placental development, intellectual disabilities and autism spectrum disorders.  

Lila C. Fleming, PhD, CHES, is a global health epidemiologist and certified health education specialist. Her research examines bullying among middle school students, adolescent risk behaviors, maternal and child health, and access to health in low- and middle-income countries (LMICs). Fleming teaches global health, applied health statistics, and public health research methods courses at Mason.

Jhumka Gupta, ScD, is a Professor in the Department of Global and Community Health within the College of Public Health. Her research program applies a social epidemiology framework toward advancing the science of gender-based violence against women and girls (e.g. intimate partner violence, sex trafficking).

Dr. Jenna R. Krall is an associate professor in the Department of Global and Community Health. Krall is a biostatistician with research interests in air pollution and environmental epidemiology.

Anna Pollack’s research focuses on the relationship between environmental chemical exposures and fertility, pregnancy, and gynecologic health. Critical to understanding these endpoints, she investigates biological mechanisms underlying these processes, such as biomarkers of oxidative stress, inflammation, and endocrine disruption

Dr. Poms is the Director of Mason Core and a professor in the Department of Global and Community Health

Dr. Roess is a professor of Global Health and Epidemiology at the Department of Global and Community Health. She is an epidemiologist with expertise in infectious diseases epidemiology, multi-disciplinary and multi-species field research and evaluating interventions to reduce the transmission and impact of infectious diseases.

Dr. Zaidi is an assistant professor in the Department of Global and Community Health. Zaidi’s research interests are primarily within causal inference, including but not limited to sufficient cause methods, sensitivity analysis, principal stratification, mediation analysis, and applications of such methods.
