I am a Ph.D. student in the Applied Geometry and Topology research group at the Centro de Investigación en Matemáticas [CIMAT] in Guanajuato under the direction of Antonio Rieser. I am working on developing homotopy theory for Limit 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, Gerardo Palafox and a group of undergrad students: Renata Capistran, Praxedis Jimenez, Román Montemayor, and Mariangel Sanchez.
About me:
I am from Monterrey, a big city in northeastern Mexico. I started my academic life as an electro-mechanical engineering student, but halfway my studies I decided to become a Math student. While completing my Math degree, I was also a Teaching Assistant at the engineering faculty for a period of two years, during which time I had the opportunity to meet people who encouraged me to continue with my studies as a graduate student at CIMAT.
