Qi Chen
PhD Candidate
Summary
🤩
RockstarQi Chen is a PhD candidate with a decade of software engineering experience specializing in optimization and solver development. Trained at Carnegie Mellon's Center for Advanced Process Decision-Making, Qi combines rigorous academic grounding with hands-on back-end engineering, contributing substantive fixes and test infrastructure to the widely used Pyomo project. Their work on GDPopt and FBBT modules shows a practical focus on robustness, logging clarity, and mathematical code generation—skills that bridge theory and production-grade tooling. Qi is comfortable navigating complex numerical codebases and improving solver reliability, an often underappreciated but critical aspect of optimization software.
