Guanpeng Li

I am an assistant professor in the Computer Science Department at the University of Iowa since 2020. Broadly speaking, my research focuses on building dependable high-performance 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 2024, 2022, 2021, 2020 and 2018, and IEEE Top Picks in Test and Reliability in 2023. I am also the recipient of the IEEE Computer Society TCHPC Early Career Researchers Award for Excellence in High-Performance Computing (2024).
