Biography

Cheryl Arrowsmith is a Senior Scientist at the Princess Margaret Cancer Centre, Professor in the Department of Medical Biophysics, University of Toronto, and the Chief Scientist of the Structural Genomics Consortium (SGC) at the University of Toronto.  Her research focuses on the structural and chemical biology of chromatin and epigenetic regulatory factors especially as relates to cancer and drug discovery. In partnership with major pharmaceutical companies, she leads the SGC’s international open science program that is developing and distributing unencumbered Chemical Probes that support the discovery of new medicines. She received her Ph.D. from the University of Toronto and carried out postdoctoral research at Stanford University, and was co-founder of Affinium Pharmaceuticals, which developed a new medicine for multidrug resistant bacteria. She has published over 300 research articles and was recognized by Clarivate Analytics as being among the worlds top 1% of highly cited scientists in 2018, 2019 and 2022. She was elected an AAAS Fellow (2015), and a Fellow of the Royal Society of Canada (2020).
