Research Interests
My current research broadly focuses on the design and analysis of provably-good algorithms for optimization under various notions of uncertainty. Application-wise, I am mostly interested in computational revenue management, electronic commerce, and business operations.
Fields: Stochastic optimization, choice modeling, applied probability, combinatorial optimization.
Techniques: Approximate dynamic programming, submodular functions, randomization, mathematical programming, polyhedral combinatorics.
Applications: Assortment planning, inventory, pricing, bioinformatics, scheduling, facility location.
