I teach quantum mechanics and spectroscopy (CHEM 44), an advanced seminar on surface chemistry and surface analysis, and I also supervise student research.
My research focuses on quantifying the interactions of single-stranded DNA on the surface of carbon nanotubes. Previous studies have shown that individual nanotube chiralities can be purified by forming suspensions using oligomers with different base sequences. We are investigating a small library of DNA sequences to fundamentally characterize the DNA sequence dependence on carbon nanotube suspension stability. We measure the kinetics of desorption of fluorescently labeled oligomers at elevated temperatures using fluorescence spectroscopy.
