Cheryl Arrowsmith is a Senior Scientist at the Princess Margaret Cancer Centre and Professor in the Department of Medical Biophysics at the University of Toronto, where she holds a Canada Research Chair in Structural Genomics. She received a Ph.D. in chemistry from the University of Toronto and carried out postdoctoral research at Stanford University in the area of protein NMR spectroscopy. Dr. Arrowsmith’s research focuses on structural and chemical biology of chromatin and epigenetic regulatory factors especially as relates to cancer. Dr. Arrowsmith is the Chief Scientist of the Toronto Node of the Structural Genomics Consortium (SGC), a multinational public-private partnership that supports the discovery of new medicines through protein-based open access research. She leads the SGC’s program to develop chemical probes to chromatin regulators for target validation.
