Patricio Guzmán

I am an Assistant Professor at the Departamento de Matemática of the Universidad Técnica Federico Santa María, which is where I got the professional title of Mathematical Engineer and later the academic degrees of M.Sci and Ph.D. in Mathematics. During my formal education I had the privilege to be directed by Eduardo Cerpa, Lionel Rosier and Alberto Mercado. My work as postdoctoral researcher at the Centro de Modelamiento Matemático of the Universidad de Chile was supervised by Axel Osses.

Research

I am interested in control theory. I am currently studying the controllability and stabilization of partial differential equations, with special interest to those coming from applied models. I participate in the following research projects.

MATH-AMSUD AMSUD220023 (National Coordinator). Stabilization, Control and Inverse Problems in PDEs.
FONDECYT 11240290 (Responsible). Rapid Stabilization of Partial Differential Equations with Disturbances.
