Biography

Prof. Nauman Ahmad Zaffar currently serves as Associate Professor and Director of Energy and Power Systems Research Cluster at Department of Electrical Engineering, SBASSE, LUMS, Lahore, Pakistan. He is also a member of the Steering Committee of LUMS Energy Institute. His areas of research include work on smarts for existing grids and new grid architectures, Power electronic converters for integration of renewable energy resources, Electrical drives, Battery storage systems and Electrical vehicles. During his tenure at LUMS, he has been engaged in launching four power electronics startups and three patents. His primary research focus is on harnessing and efficient utilization of energy from available sources such as solar PV, solar thermal, wind and hydrokinetics to enable grid independent, integrated, smart grid communities. He has worked on the chief minister’s task force on energy theft, part of the enabling team for Electricity markets for the Pakistan power sector and has been involved in formulation of National Electric Vehicle policy for Pakistan and its promulgation. He completed his undergraduate and graduate studies at University of Pennsylvania. At UPenn he worked on high resolution microwave imaging facility for radar targets with dynamic sweep of 2Ghz – 40GHz. He has also been involved in design and implementation of driver circuit for a magneto-optic spatial light modulator to be used in an optical neural network. Thereafter, he joined University of Engineering and Technology, Lahore in 1994 where he worked till 2000 as Assistant Professor in the department of Electrical Engineering. He then worked as Vice President and Head of Professional Services at Techlogix Pakistan Pvt. Limited where he headed the delivery of software solution services and design for 10 years in Pakistan, UAE, China and USA before joining LUMS in 2010.
