Instructor

Prof. Philip Kiameh performed research on power generation equipment with Atomic Energy of Canada Limited at their Chalk River and Whiteshell Nuclear Research Laboratories.  He also has more than 27 years of practical engineering experience with Ontario Power Generation (formerly, Ontario Hydro - the largest electric utility in North America). While in Ontario Hydro, Prof. Philip Kiameh worked as Training Manager, Engineering Supervisor, System Responsible Engineer and Design Engineer. During this period, he was the manager of a section that provided training for the staff at the power stations.  This training covered all the equipment and systems used in power stations.  Philip was also responsible for the operation, maintenance, diagnostics, and testing of gas turbines, steam turbines, generators, motors, transformers, inverters, valves, pumps, compressors, instrumentation and control systems. Further, his responsibilities included designing, engineering, diagnosing equipment problems and recommending solutions to repair deficiencies and improve system performance, supervising engineers, setting up preventive maintenance programs, writing Operating and Design Manuals, and commissioning new equipment. 

Professor Philip Kiameh was awarded his Bachelor of Engineering Degree "with distinction" from Dalhousie University, Halifax, Nova Scotia, Canada. He also received a Master of Applied Science in Engineering (M.A.Sc.) from the University of Ottawa, Canada. He is also a member of the Association of Professional Engineers in the province of Ontario, Canada.
