Harish Krishnaswamy

He has worked on integrated full-duplex radios that can simultaneously transmit and receive on the same frequency band, thereby doubling network capacity. He has investigated temporally-modulated circuits that break the traditional physical laws of reciprocity, enabling the realization of integrated non-reciprocal components such as isolators and circulators without the need for magnetic materials. He has also worked on integrated MIMO radios that use multiple antennas to achieve significant increase in data throughput.

He has also made significant contributions to high-power and energy-efficient millimeter-wave circuits and systems. These technologies are all of significant interest for the next generation of wireless networks (the highly anticipated “5G”). He directs the Columbia high-Speed and Millimeter-wave IC (CoSMIC) lab, where students participate in a multi-disciplinary scientific endeavor that explores synergies between the physical layer (integrated electronics) and higher layers (communication systems and networking) on the one hand, and electronics and applied physics/electromagnetics on the other.

Krishnaswamy received a B. Tech. in electrical engineering from Indian Institute of Technology - Madras in 2001, and a PhD in electrical engineering from the University of Southern California in 2009.
