I am currently a Research Fellow working with Prof. Kang G. Shin in the Real-Time Computing Laboratory in the Computer Science and Engineering Department at The University of Michigan. My research is primarily at the intersection of Autonomous Driving and Computing Systems , focusing on building safe , predictable , and energy-efficient cyber-physical systems for autonomous vehicles and autonomous mobile robots .
Before that, I got my Ph.D. degree in computer science from Wayne State University in May 2023, supervised by Prof. Weisong Shi . I have collaborated with researchers from Argonne National Laboratory, IBM Research, MIT Lincoln Laboratory, Inceptio, and Autoware.
UPDATE: I will be on the academic job market in the 2024-2025 cycle looking for tenure-track assistant professor positions. If your department is hiring, please feel free to reach out at liangkai@umich.edu .
