Supriyo Bandyopadhyay

Supriyo Bandyopadhyay is an Indian-born American electrical engineer, academic and researcher. He is Commonwealth Professor of Electrical and Computer Engineering at Virginia Commonwealth University. Bandyopadhyay has worked on a range of topics including spintronics, straintronics, nanoelectronics and related aspects of nanotechnology.

Education Bandyopadhyay received his B.Tech. degree in Electronics and Electrical Communications Engineering from Indian Institute of Technology, Kharagpur in 1980. He then earned his M.S. degree in Electrical Engineering from Southern Illinois University in 1982, and a Ph.D. degree in Electrical Engineering from Purdue University in 1985. He is a member of the Institute of Electrical and Electronics Engineers (IEEE) Technical Committee on Spintronics (Nanotechnology Council), and past-chair of the Technical Committee on Compound Semiconductor Devices and Circuits (Electron Device Society). He was an IEEE Electron Device Society Distinguished Lecturer from 2005 to 2012, and was an IEEE Nanotechnology Council Distinguished Lecturer in 2017 and 2018.

Research Bandyopadhyay has worked on spintronics, straintronics, nanoelectronics, nanosynthesis, electrochemical self-assembly, quantum dots and nanowires, hot carrier and quantum transport of charge in solids, spin based quantum computing and classical spin-based logic circuits, spin transport in nanostructures, and spin-based devices and general topics in spintronics.

Bandyopadhyay's most recent work has involved switching nanomagnets with electrically generated strain to produce energy-efficient digital information processing hardware. He worked in the field of hybrid spintronics and straintronics, His group harnessed straintronics to demonstrate an extreme sub-wavelength electromagnetic antenna that overcame the theoretical limits on antenna gain and efficiency and exceeded them by several orders of magnitude. He and his collaborators also conducted a study in 2021 to demonstrate resonant amplification of spin waves in a periodic two-dimensional interacting array of multiferroic nanomagnets which would have applications in magnonic devices.

Awards and honors 2005–2012 - Distinguished Lecturer, IEEE Electron Devices Society 2005 - Fellow, The Electrochemical Society 2005 - Fellow, American Physical Society 2006 - Fellow, American Association for the Advancement of Science 2020 - IEEE Pioneer Award in Nanotechnology: For pioneering contributions to spintronics and straintronics employing nanostructures
