Dr. Guanpeng Li

Assistant Professor
Computer Science, University of Iowa


I am an assistant professor in the Computer Science Department at the University of Iowa since 2020. I received PhD and BASc degrees from the University of British Columbia (UBC) in 2019 and 2014. Before joining the University of Iowa, I also visited the University of Illinois Urbana-Champaign (UIUC) between 2019 and 2020. My research focuses on building dependable computer systems. In the past, my students and/or I have won the Best Paper Awards (or finalists) at SC, DSN, and ISSRE conferences in 2022, 2021, 2020 and 2018. I am also on the DSN Hall of Fame.
