Matías Villagra

Matías is a first year PhD student in the IEOR Department. His research interests are algebraic methods to study discrete structures, such as polyhedra that arise from discrete optimization problems. He is broadly interested in the works of Prof. Faenza on polyhedral combinatorics, and in the works of Prof. Bienstock and Prof. Josz on polynomial optimization.

Prior to joining Columbia, he earned his master's degree in mathematics from Pontificia Universidad Católica de Chile (PUC) in 2020. Additionally, in 2016 he completed a MS and BS in economics from PUC. From 2016 until 2020 he was an instructor of economics at PUC and Universidad Adolfo Ibáñez in Santiago de Chile.
