Biography

Dr. M. Zaheeruddin obtained his B.Eng. degree in mechanical engineering from Osmania University, Hyderabad, India, in 1977, and his M.Sc. and Ph.D. degrees in mechanical engineering from the University of Alberta, Edmonton, Canada, in 1980 and 1983, respectively. He joined Concordia University in 1987 as Associate Professor. His research is in the field of energy management control systems and dynamic modeling of HVAC thermal processes.

From 1983 to 1987, he worked as a Research Associate in the Department of Electrical Engineering, University of Alberta. Since 1987 he has been a Faculty Member in the Centre for Building Studies, Concordia University, where he now holds the rank of Professor. He served on the editorial board of 'Energy', the International Journal.

Research activities

Dr. Zaheeruddin's research activities lie in the domain of HVAC and Control Systems:
  • Dynamic Modeling of HVAC Thermal Processes: This is an important area of research for improving energy efficiency and thermal comfort in buildings. Dr. Zaheeruddin has contributed in developing methodologies for state space modeling of HVAC systems and components. A significant number of developed models are used in the design, optimization, identification and model validation studies. Real-time data analysis and diagnostics are some of the ongoing research projects.
  • Energy Management Control Systems: Optimal operation of building and HVAC systems is the goal of this research. Dr.Zaheeruddin with his group conducts research in developing intelligent control strategies. Three major activities of this research are Monitoring, Control and Optimization. Significant contributions include: development of decentralized control strategies; preview and adaptive controllers; and neural network based HVAC controllers. Ongoing research projects include online tuning and intelligent controls. Implementation and testing is conducted in a HVAC and Control Systems Laboratory.
