Dr Rehan Ahmed
Assistant Professor
PhD - Electrical Engineering, University of Wisconsin-Madison, USA
RESEARCH INTERESTS

Dr Rehan's research has spanned the field of real-time/embedded systems. This field involves careful co-design of hardware and software components for a given set of requirements and constraints. Dr Rehan has researched the design and analysis of these systems, focusing on their reliability and quality of service aspects. Specific topics include thermal constrained scheduling, mixed-critical systems, energy harvesting systems, and thermal security considerations in computing platforms.

biography

Dr. Rehan Ahmed has been a part of the Computer Engineering Department at Information Technology University, Lahore, since June 2020. He completed his BSc. in Electrical Engineering from UET Lahore in 2007. Following this, he worked at LUMS SSE for one year as a Research Associate. In 2008, he went to University of Wisconsin Madison, USA, and earned his Master and a Ph.D. degree in Electrical Engineering from there in 2010 and 2015 respectively. His research at UW Madison was on Real-Time Systems. Specifically, he worked on consolidating the timing constraints of the real-time tasks with thermal constraints of the processing platform. Upon finishing his doctorate, Dr. Rehan joined TEC (Link), ETH Zurich, Switzerland as a postdoctoral researcher. As part of this group, Dr. Rehan diversified his research to include energy harvesting systems, mixed-criticality systems, and thermal security considerations, among other sub-fields. From March 2019 to May 2020, Dr. Rehan was an Assistant Professor at the Faculty of Electrical Engineering, GIK Institute.
