I am currently a postdoctoral researcher in the School of Mathematics at the University of Minnesota and a member of the Simons Initiative on the Geometry of Flows, where I work with Max Engelstein.
Previously, I was a J. J. Sylvester Assistant Professor in the Department of Mathematics at Johns Hopkins University. I received my Ph.D. in Mathematics from the University of Texas at Austin in May 2023 under the supervision of Luis Caffarelli and Francesco Maggi.
My research focuses on variational problems arising in partial differential equations, geometric measure theory, and geometric analysis.
More broadly, I am interested in problems motivated by physics and the social sciences whose structure calls for geometric methods. I also hold a Ph.D. in Economics from Universidad EAFIT (Colombia), obtained in 2022 under the supervision of Juan Carlos Duque, and I am open to multidisciplinary problems with rich geometric content.
I am currently on the job market for tenure track positions. Here is my CV.
