About

I am a 4th year Ph.D. student at Pontificia Universidad Católica de Chile (PUC), working under Giancarlo Urzúa. My research focuses on Algebraic Geometry. Previously, I was a master's student at PUC and an undergraduate student at Universidad de Los Andes under the supervision of Cristian Martínez.

Research Interests

Primarily, my research focuses on algebraic projective surfaces, with emphasis on the classification of stable limits of families of smooth projective surfaces. Using birational geometry methods, I currently study degenerations of rational surfaces.
