Professor David Zingg
Professor Zingg’s research areas include aerodynamics, computational fluid dynamics (CFD), aerodynamic shape optimization, and aerostructural optimization. His current research concentrates on both algorithm development and application of aerodynamic and aerostructural optimization to the design of unconventional low-drag aircraft configurations motivated by the need to reduce greenhouse gas emissions from aircraft. Together with colleagues from NASA, he is a co-author of the textbooks Fundamentals of Computational Fluid Dynamics and Fundamental Algorithms in Computational Fluid Dynamics, published by Springer in 2001 and 2014, respectively. He held a Tier I Canada Research Chair in Computational Aerodynamics and Environmentally Friendly Aircraft Design from 2001 to 2015 and currently holds the title of University of Toronto Distinguished Professor of Computational Aerodynamics and Sustainable Aviation. He was awarded a prestigious Guggenheim Fellowship in 2004 for research in the design of environmentally friendly aircraft, the J.J. Berry Smith Doctoral Supervision Award in 2016, and the CASI C.D. Howe Award in 2021.
