Research Projects

My research interests lie in the areas of bioanalytical and biophysical chemistry. The two main questions we are asking in my laboratory are:

  1. What are the targets and the relationship between structure and activity among antiepileptic drugs? We recently discovered that compounds containing an α-substituted amide group produce their antiepileptic effect at least in part by inhibiting the neuronal nicotinic acetylcholine receptors in the brain. An interdisciplinary approach combining rapid chemical kinetics of neurotransmitter receptors, spectroscopy, chiral HPLC and chemical crystallography is being used to elucidate the mechanism of action and solid-state chemistry of these drugs.
  2. Are there endogenous small molecules in the blood that modulate aggregation of amyloid β peptides? We use liquid chromatography, tandem mass spectrometry and Aβ(1-40) peptide aggregation assays to isolate and identify such molecules from mammalian and human blood serum.
