About 300 students of the industrial engineering undergrad program (at Universidad de Concepcion) take one of my classes each academic year. The teaching subjects I have been in charge of since 2018 are Systems Modelling, Simulation, Discrete Choice Models, and Data Interpretation. Additionally, I am in charge of the Stochastics Processes and Advanced Econometrics courses in the Ph.D. in Industrial Engineering and the MsC. in Industrial Engineering graduate programs (at Universidad de Concepcion). I have been awarded the "best teacher of the Year" at the Industrial Engineering Department (Universidad de Concepcion) for three consecutive years (2020, 2021, and 2022).

I have guided undergrad theses of more than 40 students since 2018, two MSc theses (plus two in the making), and one Ph.D. thesis.

I have been present in news and media at the local level (Concepcion, Biobio) since 2018, being a trustable voice and scientific opinion on subjects such as Sustainable Cities and Sustainable Transportation Modes.
