About

I am a Ph.D. student in Computational Applied Mathematics and Operations Research at Rice University, advised by Professor Illya V. Hicks. My research focuses on mathematical optimization, mixed-integer nonlinear optimization, and machine learning. I develop computational methods—including bound tightening, convex relaxations, cutting planes, and decomposition—for challenging decision problems in energy systems, symbolic regression, and scientific computing.

Research

Optimization algorithms

Mixed-integer nonlinear, stochastic, and fairness-constrained optimization.

Computational methods

Bound tightening, convex relaxations, cutting planes, decomposition, and branch-and-bound methods.

Applications

Energy systems, symbolic regression, multi-fidelity modeling, and scientific decision-making.
