Yunchi Lu

Hi, I am Yunchi Lu (陆云驰, Bill).

I am a second-year Ph.D. candidate in Computer Science at University of Michigan, where I am part of the Order Lab advised by Prof. Ryan Huang.

My research interests lie broadly in developing principled techniques to improve the correctness, observability, and reliability of large-scale systems. Currently, my work focuses on addressing silent bugs in various components of machine learning systems.

I received my M.S. in ECE from the University of Michigan and my B.E. in ECE from the UM-SJTU Joint Institute at Shanghai Jiao Tong University.
