Caitlin Howe

Caitlin G. Howe, PhD, is an Assistant Professor of Epidemiology at the Geisel School of Medicine, Dartmouth College. Her research focuses on the environmental and epigenetic factors influencing health, particularly the developmental origins of disease. Dr. Howe holds a PhD from Columbia University (2016) and a BA from Pomona College (2009).

Her work integrates novel methods to study how complex contaminant mixtures, such as metals and PFAS, affect early growth, cardiometabolic health, and epigenetic processes. Key contributions include analyzing extracellular vesicle miRNAs in maternal plasma and human milk, linking prenatal exposures to childhood health outcomes. Dr. Howe has also investigated the impact of maternal diet, glycemic control, and socioeconomic factors on offspring epigenetic profiles and long-term health risks.

Recent articles highlight her exploration of PFAS-induced blood pressure changes, metal mixtures' effects on fetal size, and the role of maternal depression in exposure to flame retardants. Her findings emphasize preventive strategies to reduce toxicant exposures and mitigate adverse health trajectories.

Dr. Howe collaborates extensively with interdisciplinary teams, contributing to cohorts like MADRES and NHBCS. Despite no listed scientific awards, her research has informed policy and clinical practices in environmental health and maternal-child health.
