My research deeply influences students. Students who work with me learn the tools and techniques to develop innovative models and algorithms to tackle challenging real-world problems with significant societal impact. Through research involvement and related projects, students make contributions that expand the current boundaries of knowledge. Many earn MS and PhD degrees and go on to have productive and influential careers. If you are interested in learning more, see my CV, or email me.

Current PhD Students

Narges Ahani
Data Science

I am a Ph.D. student in Data Science at WPI. I received my MS in Operation Analytics and Management from the Foisie Business School at WPI. My research interests are in the application of analytics (namely Operations Research and Machine Learning) in humanitarian fields. I am currently researching challenges in refugee resettlement, including making better decisions concerning the placement of refugees into communities, as well as efficient allocation of their available resources. I am interested in Mathematical Optimization, Machine Learning and Visualization.

Pitchaya Wiratchotisatian
Data Science

I am a Ph.D. candidate in the Data Science program at WPI. I received a BS in Mathematical Sciences with a minor in Computer Science from WPI in 2015, and an MS in Statistics from the University of Virginia in 2017. My research interest is in Mathematical Optimization, Machine Learning, and Data Mining. I am working with my advisor Dr. Andrew C. Trapp, on multiple projects using Integer Optimization. For example, I am working with WPI's Interdisciplinary and Global Studies Division to improve the optimization-based allocation tool that recommends student-to-project matches with stability, strategyproof, and cohort considerations. I am also working with Dr. Patrick Flaherty at UMass Amherst to solve the MAP estimation problem for Gaussian mixture models. We employ a mixed-integer quadratic programming model within a customized branch-and-bound algorithm.
