Dionne Aleman is the Associate Dean of Cross-Disciplinary Programs in the Faculty of Applied Science & Engineering at the University of Toronto, and is an Associate Professor in the Department of Mechanical & Industrial Engineering. She holds appointments in the UofT Institute for Health Policy, Management & Evaluation, the UofT Institute for Pandemics, and the UHN Techna Institute. She is also a co-Director of the Toronto-Manchester Joint Translational Centre for Digital Health. She received her PhD in Industrial and Systems Engineering from the University of Florida (2007), MSc from the University of Florida (2006), and BSc from the University of Florida (2003).

Dr. Aleman’s research focuses on the application of operations research to medical and healthcare systems to improve the quality, timeliness, and efficiency of care. This research includes using optimization, simulation, machine learning, and graph theory to design and validate radiation therapy treatment plans, to predict and mitigate the spread of pandemic diseases in urban populations, to improve hospital surgical scheduling, and to optimize organ transplant matches and multi-person chains. Dr. Aleman has held grants from NSERC, CFI, ORF, and NSF for her research.

She is a two-term past President of the Canadian Operational Research Society (CORS). Within INFORMS, she has served as a member of the Committee for Teaching and Learning and Chair/President of the Health Applications Society (HAS), Public Sector OR Section (PSOR), Junior Faculty Interest Group (JFIG), and INFORM-ED. Dr. Aleman has also served in editorial positions for the Wiley Encyclopedia of Operations Research and Management Science, IISE Transactions on Healthcare Systems Engineering, OMEGA, International Journal of Biomedical Data Mining, and Operations Research in Health Care.
