Research Interests


One series of ongoing studies is directed at understanding the effects of seizure disorders on heart function and the increased risk of sudden cardiac death, using an animal model of status epilepticus and temporal lobe epilepsy. A separate line of investigation is aimed at understanding the mechanisms through which these seizure disorders disrupt ovarian hormone secretion and energy balance in female rats.
