Greg Kopp is Professor of Wind Engineering.

Dr. Kopp’s research relates to mitigating damage to structures during extreme windstorms such as tornadoes and hurricanes. His expertise includes building aerodynamics, turbulent shear flows, and load effects on components and cladding. Methods include the use of model-scale wind tunnel tests, full-scale structural and component tests, and field surveys of damage.

He works actively to translate his research to the practice of engineering and, more broadly, to society. His work has been widely cited by several design standards. He is currently Chair of the ASCE 49 Standards Committee on Wind Tunnel Testing for Buildings and Other Structures and Chair of the Chapter 31 Wind Tunnel Procedure task committee of ASCE 7. His work has often been featured in the international media including the NY Times and Discovery Channel.

Qualifications

  • Registered Professional Engineer (Ontario), 1999
  • PhD in Mechanical Engineering, University of Toronto, 1995
  • MEng in Mechanical Engineering, McMaster University, 1991
  • BESc in Mechanical Engineering, University of Manitoba, 1989

Biography

Professor Kopp received a B.Sc.M.E. from the University of Manitoba in 1989, a M.Eng. from McMaster University in 1991 and a Ph.D. in Mechanical Engineering from the University of Toronto in 1995. Between 1995 and 1997 he held a NSERC Post-doctoral Fellowship in the Chemical Engineering Department at the Universitat Rovira i Virgili in Tarragona, Spain.

He returned to Canada in the summer of 1997 to an appointment of Assistant Professor at the University of Western Ontario and as a Senior Research Engineer at the Boundary Layer Wind Tunnel Laboratory. He was promoted to Professor in the Department of Civil & Environmental Engineering in July 2007 (and has a cross-appointment in the Department of Mechanical & Materials Engineering). 

He joined the University of Birmingham as Professor of Wind Engineering in 2019.

Postgraduate supervision

Dr. Kopp supervises students in all areas of wind engineering and bluff body aerodynamics.
