Professor Leggans primary responsibilities are teaching the introductory course and laboratories for the Organic Chemistry (CHM 221-222) and General Chemistry (CHM 129). His research focus is in the semi and total synthesis of biologically active natural products and the development of new synthetic methods using heterocyclic, bioorganic and medicinal chemistry. In addition to natural product synthesis, he has a keen interest in studying the natural products structure-activity relationship (SAR) and the effect that selective structural modification has on its medicinal properties.
