Bike-sharing systems are now ubiquitous across the U.S. We have worked with Motivate, the operator of the largest such systems, including in New York, Chicago and San Francisco, to innovate data-driven approaches for bike-sharing. With them we have developed methods to improve their day-to-day op...

We designed and implemented a new joint seat allocation process for over 500 programs across 80 engineering colleges in India, including the Indian Institutes of Technology (IITs). Our Deferred Acceptance-based process overcomes a number of challenges. The joint seat allocation process has been s...

We formulate the omni-channel fulfillment problem as an online optimization problem. We propose a novel algorithm for this problem based on the primal-dual schema. Our algorithm is robust: it does not require explicit demand forecasts. This is an important practical advantage in the apparel-retai...

Overfishing is a prime environmental concern. Catch share systems have recently been shown to be effective tools to combat overfishing. Yet, the allocation of catch shares has always been a challenging policy problem. There is an active discussion about market-based solutions for the allocation...

The use of unmanned aerial vehicles (UAVs) is becoming commonplace in search and rescue tasks in complex terrains. In the literature, there are a number of studies on UAV search with the objective of minimizing search time and/or maximizing detection probability. However, little effort has been d...
