David Johnson

David Johnson is a Professor in the Department of Mechanical and Mechatronics Engineering at the University of Waterloo. He leads the Wind Energy Research Group (WEG), focusing on wind turbine aerodynamics, aeroacoustics, and large-scale PIV measurement techniques. His work spans renewable energy research, including collaborations in Canada and Denmark since the 1980s.

Education:

• PhD in Mechanical Engineering, McMaster University (1994)
• MSc in Mechanical Engineering, McMaster University (1988)
• BSc in Mechanical Engineering, McMaster University (1986)

Research Interests: Johnson's research emphasizes fluid mechanics measurements, wind energy systems, and turbomachinery. His team explores blade aerodynamics, noise reduction, and turbine performance optimization using advanced experimental and computational methods. Notable projects include dynamic stall mitigation, in-blade sensor development, and wind turbine wake analysis.

Publications: Recent work focuses on trailing-edge noise prediction, yawed turbine dynamics, and LiDAR-based wake measurements. Key contributions address turbine efficiency, aeroelastic response, and control strategies for renewable energy systems.

Labs & Teams: Director of the Wind Energy Research Group (WEG), which develops innovative measurement techniques and collaborates on grid-connected turbines and off-grid hybrid systems.
