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.

I proudly collaborate teaching mathematics in the wonderful initiative, fully ran by volunteers, called Preuniversitario Solidario Santa María.

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.

Current research projects.

MATH-AMSUD MATH190008 (Researcher). Analysis, control and inverse problems for partial differential equations.

Finished research projects.

FONDECYT 3180363 (Responsible). Control of high-order partial differential equations.
ECOS-CONICYT C16E06 (Researcher). Control of distributed systems with applications in physical networks.
