My research focuses on oxidative damage to proteins and its role in neurodegeneration and aging. Oxidative damage contributes to the development of many diseases including Alzheimer’s and Parkinson’s. Currently, we are studying the interactions of native and oxidized tubulin with glycolytic enzymes and with small molecule redox regulators including nitric oxide and glutathione.
All projects in the lab use the techniques of protein biochemistry including: column chromatography for protein purification, SDS-PAGE, Western blotting, labeling of proteins with fluorescent molecules, reverse phase HPLC, and UV/Visible spectroscopy.
