About

I am currently a Ph.D. candidate in the Operations Research Center (ORC) of MIT , advised by Prof. Patrick Jaillet. I am affiliated with the Laboratory for Information and Decision Systems (LIDS), and a member of the Online Optimization and Learning research group.

Before coming to MIT, I obtained my degree in Electrical and Computer Engineering from the National Technical University of Athens in Greece, advised by Prof. Dimitris Fotakis.

My research interests are in the area of optimization and data-driven decision making, with applications in transportation and logistics.

Research

Dynamic Redistribution in Bike Sharing Systems

We propose a mixed integer programming formulation for dynamic redistribution in bike sharing systems, along with methods that are able to scale and solve large real-world instances, as demonstrated through computational experiments (Capital Bikeshare, Washington DC).

Joint work with Patrick Jaillet

Demand Estimation in Bike Sharing Systems

Accurate estimation of the user demand is essential to plan for efficient operation of bike sharing systems. To this end, we develop approaches to consider both lost and shifted demand through data-driven and optimization methods.

Joint work with Patrick Jaillet

Complex Event Scheduling

We introduce algorithms for the management and optimization of catering and other complex events across multi-building corporate campuses.

Joint work with Ishai Menache, Krishna Chintalapudi, Luke Marshall and Patrick Jaillet

Resource Scheduling for Field Services

We propose fast algorithms for the scheduling of resources for field services. A prototype of this work has been integrated in Microsoft Dynamics 365 Field Service.
