About

Education & Training

I obtained a Ph.D. in Operations Research at ISyE - Georgia Tech.  Before going to Georgia Tech, I obtained a Mathematical Engineering title (master equivalent) and a Master in Operations Management from Universidad de Chile. 

Research

Mathematical optimization, with a focus on the theory of mixed-integer programs, including properties of cutting planes and duality. 

Applications of optimization to production planning, logistics and other relevant real-world business and engineering problems. 

Lately, I have become interested in the interplay between Discrete optimization and Machine learning and Statistics.

Primary Research Focus
Discrete optimization. Theory and applications of mixed-integer linear and non-linear programming
