My research is in the general area of theoretical computer science, particularly the areas of Approximation Algorithms, Online Algorithms, and Algorithmic Game Theory. I work on developing models, algorithms, and markets for resource allocation, decision making, and provisioning problems. These problems arise in a variety of applications -- designing a data network, facility location and clustering, data center scheduling, allocating ad slots, scheduling ride-shares, and civic budgeting. In these contexts, my work has addressed several research challenges. Please see here for current projects.
Intractability: Exactly optimal solutions are often inefficient to compute due to the discrete, combinatorial nature of the problems, and we seek efficient algorithms that compute provably approximate optimal solutions.
Uncertainty: When future demand is uncertain, we seek algorithms that either work with specified models of uncertainty, or are robust to any possible future.
Pricing and Incentives: In settings where participants may lie about the utility of resources to them, we seek to design appropriate pricing schemes and incentives.
Fairness: In settings where resources are shared and the allocation has to be fair to the participants, we seek models for fairness and devise efficient algorithms for these models.
We are the local organizers for FOCS 2020.
