Dr. Noah Snyder-Mackler, PhD, is an evolutionary biologist who studies the molecular mechanisms through which environmental adversity alters aging, health, and survival. Broadly, research in his lab investigates the causes and consequences of variation in the social environment from the molecular to the organismal levels. This work involves a few complementary study systems–dogs, monkeys, and humans, which allow him to probe questions central to human health, aging, and evolutionary biology. He received his PhD from the University of Pennsylvania and is an Assistant Professor in the School of Life Sciences and the Center for Evolution and Medicine at Arizona State University.
