Biography

Zubeldia is currently a Postdoctoral Fellow in the Industrial and Systems Engineering department at the Georgia Institute of Technology, working in the research group of Siva Theja Maguluri.

Born in Montevideo, Uruguay, he received a B.S. in Electronics Engineering (2012) and a M.Sc. in Engineering (2014) from Universidad ORT Uruguay, and a Ph.D. in Electrical Engineering (2019) from the Massachusetts Institute of Technology. From 2019 to 2021, he was a Postdoc in the Department of Mathematics and Computer Science at the Eindhoven University of Technology, and in the Korteweg-de Vries Institute for Mathematics at the University of Amsterdam.

His research primarily focuses on using applied probability for the modeling, analysis, and control of large-scale stochastic decision systems, inspired by applications in computer networks, and other service and learning systems. He is particularly interested in exploring the fundamental tradeoffs between performance and efficiency that arise in these systems, with a special emphasis on the role that information plays in these tradeoffs. He was a finalist for the 2019 INFORMS APS Best Student Paper Award, and for the 2016 INFORMS George E. Nicholson Student Paper Competition.
