Greg Sun

Greg Sun is a Professor in the Department of Engineering at the University of Massachusetts Boston, where he joined the faculty in 1993. He played a pivotal role in establishing Boston's first publicly supported Engineering Program and served as the founding Chair of the Department of Engineering from 2014–2023. Dr. Sun holds a Ph.D. in Electrical Engineering from Johns Hopkins University (1993), an M.S. from Marquette University (1988), and a B.S. in Microelectronics from Beijing University (1984).

His research encompasses semiconductor optoelectronics, silicon photonics, and nanoplasmonics, with specific focus areas including:

• GeSn-based infrared photodetectors and lasers
• Quantum processes in semiconductor nanostructures
• Surface plasmon-enhanced optical devices
• Group-IV material systems (SiGeSn)
• Mid-infrared optoelectronic device design

His recent publications demonstrate strong emphasis on silicon-compatible mid-IR photonics, with innovations in GeSn photodetectors, plasmonic enhancement techniques, and electrically pumped lasers for integrated photonic systems.

Honors include:

• Fellow of Optica (formerly OSA)
• Fellow of the American Physical Society (APS)

He maintains active collaborations internationally, with visiting professorships at National Taiwan University and Academia Sinica, and serves as Deputy Editor of the Journal of Lightwave Technology.
