Director of Research
In the Ley Group, we specialise in developing new synthesis methods and applying them to the construction of biologically important molecules. Over the years we have completed the total synthesis of many natural products, including: spongistatin 1 (anti-mitotic agent); rapamycin (immunosuppressant); thapsigargin (SERCA pumps inhibitor); azadirachtin (insect antifeedant); and bengazole A (fungicide). In addition to our research on natural product synthesis, we also pioneered flow chemistry and machine assisted synthesis.
For more detailed research information and our publication list, please see our legacy group website.
