Dr. Knickmeyer’s lab investigates the impact of genetic and hormonal variation on neurodevelopmental trajectories and risk for psychiatric disorders. She is currently leading a project which is applying cutting-edge techniques in genomics to a sample of 900 children who received high-resolution MRI of the brain at 2 weeks of age and utilizing next-generation sequencing to identify rare variants influencing brain development. She is also using MRI to characterize sexual differentiation of the brain, to evaluate the effects of prenatal exposure to antidepressant medications, and to study infants with Turner Syndrome, a remarkable participant group who can help us determine the role of sex hormones and X-chromosome genes on early brain development.
