Kathryn L. Humphreys

Assistant Professor, Dept. of Psychology and Human Development

Dr. Humphreys trained as a clinical psychologist and has expertise in infant mental health. Her work centers on identifying pathways to psychopathology and other negative outcomes. Given the importance of early experience and plasticity of the developing brain, she focuses on caregiving experiences in early life, with a particular interest in identifying targets for prevention and intervention programs. Her research includes tools from neuroscience, including magnetic resonance imaging, in infants, children, and adults, as well as biological markers of aging and health.
