Cell Signaling and Carcinogenesis
Cell Signaling and CarcinogenesisOur lab is dedicated to investigating the intricate dynamics of Wnt signaling in development, specifically focusing on the functional mechanisms of the Wnt receptor complex at the cell membrane. This complex orchestrates both canonical and non-canonical Wnt signaling pathways, which are crucial for regulating cell fate, proliferation and tissue patterning during development.
We are particularly interested in how alterations in Wnt-related genes affect signaling outcomes and contribute to developmental disorders like Robinow syndrome, where mutations in Wnt pathway components lead to distinct skeletal and facial abnormalities. By dissecting how variants in Wnt genes disrupt these signaling pathways, we aim to enhance our understanding of their role in development.
Furthermore, given that aberrant Wnt signaling is a well-established cancer driver regulating cell growth and differentiation, our research also seeks to bridge these developmental insights with cancer biology, potentially uncovering new therapeutic avenues for genetic syndromes and malignancies.

Biography
Dr. Williams received his Ph.D. in biology from Massachusetts Institute of Technology in 1996, where he trained with Tyler Jacks. For three years, he was a postdoctoral fellow at the National Institutes of Health in the laboratory of Harold Varmus, former Director of NIH. Dr. Williams joined VAI as a scientific investigator in July 1999. He was promoted to professor in 2013 and served as chair of VAI’s Department of Cell Biology from 2010 to 2022. In 2022, he was appointed director of VAI’s Core Technologies and Services, which provides leading-edge shared scientific resources to bolster research at the Institute and beyond.
