Our laboratory focuses on the general problem of specific molecular recognition in biological systems. Our work begins with structure, but we are very interested in pushing and extending the measurement envelope so that we obtain a fundamental understanding of the energetic basis for molecular recognition. Accordingly, we use a wide breadth of molecular, genetic and biophysical approaches that together shed light on aspects of molecular recognition that are not apparent from structural studies alone. Our long range goal is to use this understanding to design novel small molecules that alter biological pathways within a cellular environment. One approach we are developing is the high-throughput synthesis and screening of small molecule libraries directed at important targets in cancer and viral pathogenesis.
