Early life and education

Ehsanur Rahman completed his Bachelor of Science (2014) and Master of Science (2016) degrees in Electrical and Electronic Engineering from Bangladesh University of Engineering and Technology (BUET)^[2]. He subsequently earned a Ph.D. in Electrical and Computer Engineering from the University of British Columbia (UBC), Canada, in 2022^[2], with a research focus on heat-to-electricity conversion in renewable energy systems^[3]. During his doctoral studies, he was awarded the Vanier Canada Graduate Scholarship, Canada’s most prestigious Doctoral Fellowship. Following the completion of his Ph.D., he received the Natural Sciences and Engineering Research Council (NSERC) Postdoctoral Fellowship.

Academic career

Ehsanur Rahman began his academic career at the Bangladesh University of Engineering and Technology (BUET) in 2014, joining the Department of Electrical and Electronic Engineering as a Lecturer^[1]. He was promoted to Assistant Professor in 2017^[1]. Between 2018 and 2022, while undertaking his doctoral studies, he was affiliated with the Stewart Blusson Quantum Matter Institute (SBQMI) at the University of British Columbia^[4]. During this period, he also completed an internship in electrical machine design at Ansys Inc^[2]. At BUET, Rahman is involved in both undergraduate and postgraduate teaching^[5]. At BUET, Dr. Rahman leads the PHENIX Lab (Photonics & High-Efficiency Nanoelectronics Innovations Laboratory)^[6], focusing on next-generation nanoscale devices for energy conversion, computing, and sensing. His research lies at the interface of electronics and photonics, with emphasis on quantum transport, hybrid optoelectronics, and thermophotonic systems that harness photon-electron interactions for high-efficiency applications.

During his PhD at the University of British Columbia (UBC), he received several honors, including the J. K. Zee Memorial Fellowship, the Faculty of Applied Science Graduate Award, President's Academic Excellence Initiative PhD Award, and the International Doctoral Fellowship. In 2019, Dr. Rahman was awarded the Vanier Canada Graduate Scholarship by NSERC for his doctoral research on thermionic and photonic energy conversion systems. Earlier in his academic career, Dr. Rahman was placed on the Dean’s List and awarded the University Merit Scholarship from BUET for outstanding academic performance in his undergraduate studies at BUET.

Professional involvement

Dr. Rahman has also actively contributed to the academic and professional community through peer review, conference leadership, and national-level consultancy. He has served as a peer reviewer for several international journals and conferences, including Energy Conversion and Management, IEEE Transactions on Electron Devices, Applied Thermal Engineering, IEEE International Conference on Telecommunications and Photonics, and International Conference on Electrical and Computer Engineering. He was the Session Chair for the Renewable Energy track at ICECE 2024 and has been a member of the organizing committees for both the 13th and 8th editions of the ICECE in 2024 and 2014, respectively. In 2015, Dr. Rahman served as Treasurer of the IEEE Electron Devices and Solid-State Circuits Society, Bangladesh Chapter, and as the Membership Development Coordinator for the IEEE Young Professionals, Bangladesh Section.

In addition to his academic roles, Dr. Rahman has participated in various national consultancy projects under the Bureau of Research, Testing and Consultation (BRTC) at BUET. These include feasibility studies for establishing the National Academy of Advanced Telecommunication Research and Training; Fire and life safety assessments for the Patenga Container Terminal; Grid-impact studies for the DSEPL solar power plant and BSRM arc furnace on behalf of the Power Grid Company of Bangladesh(PGCB); Electrical Service Design for the new academic building at the Bangladesh University of Textiles (BUTEX); and leading the Impact Assessment Study of a 132 kV PGCB transmission line on human health, requested by the Bangladesh Armed Forces.
