- How the distribution of alkyl groups affects the stability of allyl and pentadienyl carbocations
- How the multistep carbocation rearrangement involved in the transformation of caryolanol to isoclovene takes place
- How phenylalanine (in addition to the well-known cases of tyrosine, tryptophan, and histidine) can act as a radical cation "stepping stone" for the transmission of charge (as electron "holes") through a peptide (This project is a collaboration with groups in Fribourg, Switzerland and Melbourne, Australia)
- Assessment of how well various functional groups might serve as isosteric replacements for a diaryl thioether (which is susceptible to in Vivo degradation) in pharmaceuticals (This project is a collaboration with the Knapp research group at Rutgers University)
