Professional Interests

Dr. Howe’s research focuses on toxic metal exposures and their impacts on maternal and child health, with a particular interest in effects on early life growth and cardiometabolic health. Additional areas of interest include epigenetic mediators of toxicant exposures and metals toxicity in the context of nutritional status and complex environmental mixtures.

Grant Information

Prenatal Metal Mixtures, Fetal Growth, and the Role of MicroRNAs (NIEHS)


Professor Howe received her BA in 2009 from Pomona College, with a major in Biology and a minor in Spanish. After graduating, she worked at Fox Chase Cancer Center in an ovarian cancer research lab. She subsequently pursued a PhD in Environmental Health Sciences at Columbia University's Mailman School of Public Health. After receiving her PhD in 2016, she completed a postdoctoral research fellowship in the Department of Preventive Medicine at the University of Southern California. In 2020, she was appointed to the faculty at the Geisel School of Medicine.
