Bio

"Dr. Roy received his Ph.D. at the School of Industrial Engineering at Purdue University. He was concurrently a Pre-Doctoral Fellow in the Department of Industrial Engineering and Management Sciences at Northwestern University. Dr. Roy also received his B.S. in Industrial Engineering from Purdue University.  His research area focuses on optimal decision-making under uncertainty with applications in cancer radiation therapy.  For his research, he has collaborated with and was imbedded in the radiation oncology departments of the Indiana University Cancer Center, as well as, the Northwestern Memorial Hospital. He has received Purdue's highest Excellence in Teaching award both in 2012 and in 2013. He has received the Best Regional Paper Award from the American Association of Physicists in Medicine symposium in 2013 and the best poster award at the Health System Optimization Workshop in 2014.

In addition to teaching and research endeavours, Dr. Roy is a member of international organizations such as Institute for Operations Research and the Management Sciences (INFORMS) and American Association of Physicists in Medicine (AAPM)."

My Primary research area is in robust decision-making with focus on robust optimization and robust analytics. Application areas include:

  • Radiation Therapy
  • Healthcare Delivery System
