Academic Profile

Yuanjie (Roger) Xia

PhD Candidate | SENSE Lab, University of Waterloo

I am a PhD candidate at University of Waterloo working in the SENSE Lab. My research focuses on software engineering, with broader interests in performance testing, search-based method, and root cause detection.

My current work explores performance modeling in configurable systems. I am especially interested in methods for modeling system performance behavior and locating performance regressions.

I am open to discussion and collaboration.
