He joined as a Lecturer in the Dept. of EEE, BUET in 2009 and completed his Ph.D. in Electrical Engineering from the University of Michigan, Ann Arbor between 2012 and 2016. During his Ph.D. research, he was a member of the team which experimentally demonstrated the first room-temperature electrically driven polariton laser in 2014. He, along with his co-workers, also experimentally demonstrated the first high-speed modulation of a polariton laser and its output polarization control employing spin-selective contacts. His current research interests lie in the area of solid-state electronics, with focus on photonics, optoelectronics, spintronics and spin-optoelectronics.
