I am currently a PhD candidate in Operations Research at the Georgia Institute of Technology. Before coming to Georgia Tech, I have obtained my bachelor’s and master’s degrees from the University of Oxford.

I am broadly interested in utilizing and developing OR techniques for practical applications, especially ones related to healthcare. Throughout my PhD, I have worked on a wide variety of topics. In an academic setting, I engaged in research on epidemiology, and ranking and selection. In a more industrial context, I developed solutions for ecommerce and routing.

Teaching Experience

ISYE 3133 Engineering Optimization

Graduate Student Instructor, Georgia Tech

Cotaught with Prof. Santanu Dey and Prof. Natashia Boland.

I taught two sections per semester of about 30 students each. I held weekly problem solving session focused on linear and integer programming. I also helped to develop course material aimed at introducing students to optimization software and modelling interfaces.

Graduate Teaching Assistant, Georgia Tech

Teaching assistant for Prof. Sigrun Andradottir.

I graded homework and helped with some content. I also covered a lecture on Continuous Time Markov Chains.

Work Experience

Research Intern

Microsoft Research

I worked with Luke Marshall to come up with practical approaches for integrating risk calculations into technician routing and scheduling. We developed efficient algorithmic methodology to tackle the variant of the problem with hard time windows and time-dependet travel times. The paper, code, and data are in the process of being released.

I worked with Ishai Menache on the problem of distributed order management. Along with other collaborators, we developed asymptotically optimal approximation algorithms for variants of the problem.

I also designed more practical heuristics for use by Dynamics 365. This aspect of the project has been integrated into October 2018 release. It was presented during Microsoft Ignite. Relevant parts of the presentation are here:
