Areas of Research Interests
My research, in collaboration with the Farber and Wozniak labs, focuses on drug-induced neuropathology in the developing brain. Due to the intricate ontogenetic processes that occur during brain formation, drugs that are normally safe in the adult can be extremely toxic to the immature brain. Much of this work is based on the pioneering work done by my mentor, Professor John Olney (recently deceased), who I have collaborated closely with and plan to continue his research. Using animal models, we have found anesthetics are relatively safe in the adult but can be highly toxic to the developing brain. This suggests anesthesia may have adverse effects for over a million children that are exposed to anesthesia every year. This concept has recently been bolstered by several retrospective clinical studies showing children exposed to anesthesia exhibit neurodevelopmental impairment. However, it is important to acknowledge that anesthesia is oftentimes an important and necessary component of perinatal medicine. Therefore, we are characterizing when the developing brain is susceptible to this toxicity and working on safer ways to administer anesthesia. Beyond anesthetics, we have found other pharmacologically related drugs can also produce similar neurotoxic effects. These include drugs of abuse (such as alcohol, phencyclidine, and ketamine), sedatives, and anti-epileptic drugs. Therefore, we are also characterizing the adverse effects produced by these related drugs.

Finally, I have also found glucocorticoids can be toxic to the developing brain. Approximately 10% of prematurely born infants receive glucocorticoid therapy to treat respiratory dysfunction associated with premature birth. However, clinical exposure to these drugs can cause permanent neuromotor/cognitive deficits and selective cerebellar stunting. Using animal models, we have found exposure to glucocorticoids produces rapid apoptosis in the neural progenitor cells of cerebellar external granule layer and permanent stunting of the cerebellum. Since these progenitors are responsible for producing over 90% of the neurons in the developing cerebellum, this toxicity may explain many of the behavioral deficits associated with glucocorticoid therapy. Like anesthesia, glucocorticoids are oftentimes an important part of appropriate perinatal care. Therefore, we are also working on safer ways to administer this therapy.
