I did my Ph.D. at the Centro de Investigación en Matemáticas [CIMAT] in Guanajuato under the direction of Antonio Rieser in the Applied Geometry and Topology research group. I am working on developing homotopy theory for Pseudtotopological and Čech Closure spaces and applications to Topological Data Analysis [TDA].
I am also interested in coarse geometry. In my Master's thesis; also under the direction of Antonio Rieser, I explored Semi-Coarse Spaces, a variation of Coarse Spaces. We defined an interesting notion of homotopy in that category and constructed a natural Vietoris-Rips homology that is invariant with respect to this homotopy.
I am working as a part-time professor at Universidad Autónoma de Nuevo León [UANL], where I am giving initial courses of basic math to under-graduated students. Here, I am co-organizing a Student Seminar joint with Gerardo Hernández and Gerardo Palafox.
