Organic Chemistry

Research in the Gust group focuses on organic photochemistry and synthetic and physical organic chemistry. We apply the techniques of organic synthesis, laser spectroscopy, and (photo)electrochemistry to the solution of problems in these areas. Much of our research is carried out in the Center for Bio-Inspired Solar Fuel Production (BISfuel), which is a DOE-sponsored Energy Frontier Research Center. The work involves artificial photosynthesis: the design and construction of complete experimental systems for using solar energy to oxidize water and produce hydrogen or other useful fuels. Other work in the group involves the use of photochromic molecules, which change structure upon absorption of light, for applications in molecular logic and computing, and in photochemical control of molecular function and photoprotection . A third general research area is the molecular mechanisms of bird navigation using the earth's magnetic field and related magnetic phenomena. Research in the Gust group is highly interdisciplinary, and often involves collaboration with other groups in biochemistry, materials science, physics and engineering. Students either specialize in one technique and thereby contribute to the solution of a variety of group research challenges, or become more generalized, learning about a variety of different techniques and areas of expertise.
