William Que was an assistant professor in the Faculty of Mathematics, Physics & Computer Science at Ryerson University from 2000 to 2005. Que received his PhD in solid state physics from Virginia Tech after being awarded the prestigious China-U.S. Physics Examination and Application program (CUSPEA) scholarship to pursue graduate studies in physics in the United States. Following graduation, Que was a postdoctoral fellow at Simon Fraser University, Beijing University and the University of Toronto. He joined John Rowland’s imaging physics group at the Sunnybrook and Women’s College Health Sciences Center in 1994, making a transition into Medical Physics. After completing a medical physics residency, he joined the medical physics staff at the Toronto Sunnybrook Regional Cancer Center (TSRCC), a position he maintained part-time while a professor at Ryerson. He published over 35 refereed scientific papers, 21 abstracts and co-authored the book "Solid State Physics for Engineers," published in 2003. Que became known for his work in radiotherapy. He managed the technical aspects of the iodine-125 seed implant program at TSRCC and was awarded the 2001 Elekta prize for the best paper in the Journal of Applied Clinical Physics for work in that area. Que passed away suddenly in 2005.
