Curriculum Vitae


Castle Research Group

Our research is focused on the total synthesis of architecturally complex bioactive natural products and peptides.  We believe that the structures of such compounds can serve as inspiration for the invention of new organic reactions and processes.  Additionally, studies of their biological activity can increase our understanding of their modes of action, potentially leading to the design and development of new therapeutic agents.  Some of our recent synthetic targets are shown below.

Additional research areas: Bioorganic, Cancer Research, Medicinal and Natural Products
