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.
