Wenjie Xiao

My main interests are in convex optimization and first-order methods, with a focus on Frank-Wolfe algorithms for continuous problems and the Boscia framework for tackling mixed-integer optimization problems.

🔬 Projects

Research Campus MODAL SynLab

This project develops the SCIP Optimization Suite and generalizes application-specific advances from MODAL's vertical labs into exact methods for constraint integer programming. The focus is on structure recognition, nonlinear constraints, and efficient implementation on modern architectures.
