Research in the Hughes lab focuses on the development of protein and small molecule-based reagents for the control and monitoring of biochemical pathways. One project in our lab focuses on the development light-activated biosensors for the detection of oxidative stress (a precursor/predictor of numerous degenerative diseases) in cells. A second project is aimed at developing environmentally sensitive protein-based reagents that initiate biochemical pathways ending in cell death. Finally, we are developing library-based methods for the production of improved protein chimera via a linker optimization strategy. Other areas of interest include methods for the design and selection of improved biocatalysts.
Students performing research in our lab will have access to a wide variety of experimental techniques, including PCR, molecular cloning, protein expression and purification, western blotting, cell culture, fluorescence microscopy, and numerous biochemical assays.
