Research Interest

Our primary tools for studying neuronal responses have been electrophysiological using patch-clamp whole cell recordings in single neurons in brain slices and primary neuronal cell cultures. Most of this work has been supported by peer-reviewed NIH grants from the National Institutes of Alcohol Abuse and Alcoholism.

  • Understanding the neuropharmacology of intoxication, tolerance and dependence, including epilepsy-like withdrawal seizures.  How do alcohols (ethanol), change central nervous system (CNS) function through direct molecular level actions on the brain?  How does alcohol activate brain adaptive responses in neurotransmitter systems and neurocircuits of the nervous system to cause acute and chronic resistance to intoxication (e.g. tolerance) and the physical requirement for ethanol (e.g. dependence) that triggers the withdrawal syndrome (e.g., DTs) including transient life threatening grand mal seizures?
  • Understanding the neurotoxicology of Fetal Alcohol Syndrome (FAS) to identify therapeutic interventions that protect / improve brain function of children at risk for Fetal Alcohol Spectrum Disorders (FASD) injury. What causes the fetal alcohol syndrome / fetal alcohol spectrum disorder where intoxication disrupts critical periods of neuronal development and causes lasting impairment of cognitive brain function?  How does ethanol distort receptors for the neurotransmitter gamma-aminobutyric acid (GABA) in the young brain, which is also an alcohol target in the adult brain? What is the impact of ethanol on the formation and refinement of brain synapses?  Can therapeutic interventions protect brain connections and activity as well as preserve cognitive function? 

I participate in graduate training as a member of the faculty in the Interdisciplinary Program in Neuroscience.
