Dr. Ehsanur Rahman

Welcome to my academic website. 

I am an Assistant Professor in the Department of Electrical and Electronic Engineering at Bangladesh University of Engineering and Technology (BUET).  I received both my B.Sc. and M.Sc. degrees in Electrical and Electronic Engineering from BUET. Driven by a strong interest in sustainable and clean energy technologies, I pursued a Ph.D. in Electrical and Computer Engineering at the University of British Columbia (UBC), Canada, where my research focused on static heat-to-electricity conversion mechanisms. During my doctoral studies, I was honoured to receive the Vanier Canada Graduate Scholarship, Canada’s most prestigious and competitive doctoral award, recognizing outstanding academic achievement, research potential, and leadership. In addition, I was awarded both the International Doctoral Fellowship and Four Year Doctoral Fellowship from UBC, further acknowledging my academic excellence and promise as a researcher. To complement my academic training with practical experience in industry-standard simulation tools, I completed a research internship in electrical motor design at Ansys Inc. in Pennsylvania, USA, where I worked on advanced modeling and performance analysis of electrical machines.

Following the completion of my Ph.D., I received a Postdoctoral Fellowship from the Natural Sciences and Engineering Research Council of Canada (NSERC), which supported my continued research on advanced energy conversion technologies.

At BUET, I lead the PHENIX Lab (Photonics & High-Efficiency Nanoelectronics Innovation Laboratory), where we investigate the design and performance of next-generation nanoscale devices at the interface of electronics and photonics. Our research spans quantum and nanotechnologies, aiming to develop ultra-efficient and high-performance systems for computing, energy harvesting, communications, and sensing. Key focus areas include novel transistor architectures, hybrid optoelectronic platforms, and thermophotonic energy conversion systems exploting the interplay between photons and electorns. PHENIX Lab strives to advance foundational knowledge while translating scientific discoveries into impactful innovations—igniting progress at the intersection of light and charge.
