Dr. Nasser Ashgriz is a professor of Mechanical & Industrial Engineering at the University of Toronto. Prior to U of T, he was a Professor of Mechanical and Aerospace Engineering at the State University of New York at Buffalo, Buffalo, New York. He obtained his BS (1979), MS (1981), and PhD (1984) degrees in Mechanical Engineering from Carnegie-Mellon University, Pittsburgh, PA, where he was the recipient of two Bennet Prize awards (1981, 1983) in recognition of outstanding scholarly work in Mechanical Engineering.

He has been a visiting scientist at several national laboratories including NASA Lewis Research Center and Phillips Laboratory at Edwards Air Force Base. He has received several awards including the Ralph Teetor Award from Society of Automotive Engineers (1988), The Best Picture Award, from the American Physical Society (1988), the Best Paper Award, from the Combustion Institute (1992), and TOKTEN Award from the United Nations Development Program (1995). He is also the holder of a patent on MultiOrifice Impulsed Spray Generator, Patent No. 4,667,877. Dr. Ashgriz has been a member and has held offices in various professional societies (e.g., ASME K-11 Committee, "Heat Transfer in Fire and Combustion Systems," ASME Winter Annual Meeting, American Physical Society, the Combustion Institute, and the Institute for Liquid Atomization and Spray Systems).

Dr. Neumann has received his Dr.rer.nat in Chemical Physics, at University of Mainz, Germany in 1962, his habilitation in Physical Chemistry of Surfaces, at University of Stuttgart, Germany, 1972. He is currently Professor Emeritus of the Department of Mechanical & Industrial Engineering, University of Toronto.

During his career he has produced approximately 450 publications. His research interests include: Fundamental surface thermodynamic studies from both experimental and theoretical points of view, including: contact angle phenomena and surface energetic; Development of novel methodologies in applied surface thermodynamics: Application of image analysis and computer-aided techniques in measurements of surface thermodynamic properties such as surface tension, contact angle, and line tension; Applications of thermodynamics to process of biomedical relevance: Novel methodology for the energetic characterization of biosurfaces, most recently in lung physiology, specifically the role and function of lung surfactants.
