Free Radical Chemistry
Text Box: Group

The reactions of free radicals has long captured the attention of organic chemists. Radicals are used to make the bulk of the world’s polymers, are responsible for the deterioration of essentially all petroleum-derived products, from polymers to lubricating oils, and are even used to carry out complex synthetic transformations. The intervention of radical intermediates in biological contexts also attracts widespread interest due to their role in aging, the development of degenerative diseases, and the processes that drive life: respiration and photosynthesis. In our lab, we make use of synthetic organic chemistry coupled with the concepts and tools of physical organic chemistry and even molecular biology to address questions involving radicals in organic and biological chemistry. We currently have four particular foci:
