We are saddened to announce that our colleague and friend Tom Coleman, Professor of Combinatorics and Optimization at University of Waterloo, passed away on April 20 after a battle with cancer. Tom was a pioneer in many aspects of optimization and scientific computing including combinatorial scientific computing, parallel optimization, automatic differentiation, and portfolio optimization. In addition to his influential scientific work including eight books, he was an advisor and mentor to dozens of masters, PhD and postdoctoral students. He also served in multiple leadership roles in our community, including as Director of the Cornell Theory Center and as Dean of Mathematics at Waterloo, and was awarded several honors including SIAM Fellow and the Ophelia Lazaridis University Research Chair at Waterloo. He will be greatly missed. A longer biography will appear soon on the University of Waterloo C&O department website.
A private family memorial service will be held on Monday, April 26 10 AM EDT; the service will be livestreamed and friends are invited to participate. An obituary and information on joining the livestreamed memorial service are available here.
