Stephen is a senior research scientist in the Center for Therapeutics Discovery and at the Stanford Cancer Institute. At Stanford, his work focuses on using chemically induced proximity to discover powerful new pharmacology. He also drives challenging medicinal chemistry projects focused on high-value clinical targets. Before this, he was an undergraduate at Stanford and received a Ph.D. at Harvard from the Program in Genetics and Genomics, where he made contributions to the fields of cohesin biology and chromosome organization. After this, Stephen was a Helen Hay Whitney Postdoctoral Fellow supported by the Howard Hughes Medical Institute at Harvard Medical School, where he used cryo-EM to determine the molecular structures of protein complexes that underlie genetic inheritance in normal and cancerous cells.
