Curriculum Vitae

Research:

The Castle Research Group is focused on the total synthesis of architecturally complex bioactive natural products and peptides. The Group believes 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 science's understanding of their modes of action, potentially leading to the design and development of new therapeutic agents.  Some of Castle Reseach Group's recent synthetic targets are shown below.

The Castle Research Group also focuses on bioorganic chemistry, cancer research, and medicinal and natural products.
