About me

I was born in September 24th, 1992 in Viña del Mar, Chile. In November 2016 I received the MSc. in Electronic Engineering degree with a major in Automatic Control, together with my Electronics Engineering degree, at Universidad Técnica Federico Santa María (UTFSM) in Valparaíso, Chile.

In October 2017, I began my Ph.D. studies at KTH under the supervision of Cristian R. Rojas. I successfully defended my Ph.D. Thesis in May 2022, with title "Continuous-time System Identification: Refined Instrumental Variables and Sampling Assumptions". My main interests are among the areas of system identification, signal processing, and control theory. I am currently a postdoctoral researcher in the Control Systems Technology Group at Eindhoven University of Technology, the Netherlands.

Among other interests, I enjoy reading, running, playing soccer and chess. I also like playing guitar (acoustic and electric) and bass (fretted and fretless).
