Biography

BIOGRAPHICAL SKETCH: Dr. Wilson received her bachelor of arts in both art and physiology from the University of California at Berkeley before coming to Johns Hopkins for a doctoral degree in biochemistry, cellular and molecular biology, which she received in 1990. She held post-doctoral fellowships at Hopkins’ Department of Neuroscience and Kennedy Krieger Institute's developmental neuroscience lab before joining the research faculty at Kennedy Krieger Institute in 1994. Dr. Wilson was elected to Phi Beta Kappa at UC-Berkeley in 1982, and received her degree in physiology with honors. She was awarded a pre-doctoral fellowship in systems and integrative biology at UC-Berkely in 1982, and was awarded a pre-doctoral fellowship in biochemistry, cellular and molecular biology at Hopkins in 1983. RESEARCH SUMMARY: Neurodevelopmental disorders such as cerebral palsy and autism are common chronic childhood disorders with no effective cure. Half a million children under the age of 18 in the United States have cerebral palsy, and one in 6 children have some form of developmental disability. In term infants that suffer asphyxia at birth, low oxygen levels and low blood flow can cause hypoxic-ischemic encephalopathy, which is a major cause of cerebral palsy and related disabilities. Dr. Wilson’s research is focused on reducing brain damage in infants exposed to perinatal hypoxia-ischemia. Therapeutic hypothermia is the first intervention to reduce brain injury in term infants after perinatal asphyxia, but protection is typically incomplete and rates of mortality and severe disability remain high. There remains a critical need for complementary therapies that improve neuroprotection and address the negative effects of hypothermia and rewarming. Dr. Wilson investigates molecular mechanisms of hypoxic ischemic injury in the developing brain and neuroprotective effects of drugs, hypoxic preconditioning, and hypothermia. She has investigated how changes in gene expression after a brief period of hypoxia reduce the vulnerability of the brain to a later, more severe HI insult. She also studies sex differences in brain injury mechanisms that are triggered by hypoxic ischemic injury in neonatal mice and has shown that there are sex-specific differences in the neuroprotective effects of some therapeutic interventions. Dr. Wilson’s current work investigates the neuroprotective mechanisms engaged by hypothermia in neonates, with the goal of developing complementary therapies that enhance hypothermic neuroprotection.
