Biosketch

Lewis Tseng is an associate professor in the department of Electrical & Computer Engineering at UMass Lowell. Before joining UMass Lowell in September 2024, he was with Clark University, Boston College, and Toyota InfoTechnology Center. His research group designs and builds high-performance fault-tolerant distributed systems, by identifying principles for distributed coordination primitives. His research in these areas has been sponsored by the National Science Foundation, Toyota InfoTechnology Center, and the Schiller Institute at Boston College.

He was a recipient of the National Science Foundation Faculty Early Career Development (CAREER) award (2023). He was also a recipient of the Illumination Award (2022) and Teaching-Advising-Mentoring grant (2022) at Boston College. He has won the best paper award at SSS 2017.

He is active in academic service. He regularly serves as the technical program committee (TPC) member for leading IEEE and ACM conferences including ACM PODC, IEEE ICDCS, IEEE ICC, and IEEE GLOBECOM. In 2022, he co-organized ACM SPAA. He has also been frequently serving on panels for NSF programs. Currently, he serves as the Area chair of Journal of Systems Research (JSys).
