Research Interests

In the broadest sense, I do research regarding how to bridge operations research and machine learning together for solving complex real-world systems under uncertainty.
  • Data-Driven Optimization under Uncertainty

    • Distributionally Robust Optimization (DRO)

    • Predict-then-Optimize (PTO)

  • Machine Learning

    • Machine Learning for Combinatorial Optimization (ML4CO)

    • Knowledge and Data-Assisted Metaheuristic

    • Surrogate-Assisted Optimization

  • Real-world applications in facility location, sensor networks management, routing problems, etc.
