Dr. Knickmeyer, Associate Professor in the College of Human Medicine’s Department of Pediatrics and Human Development, has spent 20 years working at the cutting edge of cognitive developmental neuroscience, integrating pediatric neuroimaging and behavioral assessments with state-of-the-art techniques in genomics, metagenomics, and analytical chemistry. She is especially interested in the first 1,000 days of life (conception to late toddlerhood), a unique period of vulnerability and opportunity for the developing child. Current projects in her lab address genetic influences on infant brain development, sexual differentiation of the human brain, and the development of the microbiome-gut-brain axis. Ultimately, Dr. Knickmeyer hopes to develop therapeutic interventions which could normalize adverse neurodevelopmental trajectories in infancy and early childhood, thereby preventing the onset of psychiatric and neurodevelopmental disorders or reducing their severity. She encourages potential collaborators and talented students and postdocs to contact her about research opportunities.
