Martin Zubeldia

About me

I am an Assistant Professor in the department of Industrial and Systems Engineering (ISyE) at the University of Minnesota.

Before joining the University of Minnesota, I spent a year as a Postdoctoral Fellow in the department of Industrial and Systems Engineering at the Georgia Institute of Technology, and two years as 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. I received my PhD in Electrical Engineering from the Massachusetts Institute of Technology in 2019, where I was lucky to be advised by David Gamarnik and John Tsitsiklis.

My research primarily focuses on using applied probability for the modeling, analysis, and control of large-scale stochastic decision and learning systems. I am particularly interested in exploring the fundamental tradeoffs between performance, efficiency, and scalability that arise in these systems, and in how we can combine traditional model-based analysis with newer data-centric approaches to get the best of both worlds.

If you are a student at the University of Minnesota, and interested in working at the interface of applied probability, machine learning, and networking, please reach out to me.
