About Dr. Dhiraj Sinha

Dr. Dhiraj Sinha is an Assistant Professor at Plaksha University.  He studied electrical engineering at the Institute of Engineering and Technology, University of Lucknow, India and Telecommunications at ENST de Bretagne, Brest, France. He later earned a PhD in Electrical Engineering from University of Cambridge, UK. During the latter part of his stay at Cambridge and as the CTO of Smantenna Ltd, a thin film based antenna startup, he worked on research and commercialization of thin film based antennas. This was followed by a brief stint at Oscion, a technology consulting firm, following which he joined the Singapore University of Technology and Design, Singapore as a Research Fellow.

Research

Dr. Sinha's research interests are converged towards radiating structures with low degrees of freedom. He has explored ultra-small antenna design and sensing, besides investigating thermodynamics and electromagnetic field effects in microscopic systems with low dimensions.
