Professional Interests

Dr. Howe’s research investigates how environmental and epigenetic factors shape health with a focus on the developmental origins of disease. Her research applies novel methods for evaluating how complex mixtures of contaminants, especially metals, impact early growth and cardiometabolic health. She also uses bioinformatic approaches to assess how exposures in utero and early childhood affect the epigenome and transcriptome, and in turn children’s health. Through this work, Dr. Howe aims to identify preventive strategies that improve long-term health, including interventions that reduce toxicant exposures and protect against their effects.

Biography

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.
