Enrique G Alvarado

Welcome to my mathematics home page! I am a tenure track assistant professor at the Mathematical Sciences Department at UT El Paso. Before UTEP, I was a postdoc at Iowa State University working with my mentor, Eric Weber, on applying topological data analysis (TDA) techniques to spatio-temporal datasets (NSF grant #2219959). Before ISU, I was a postdoc at UC Davis for 3 years, where I worked with my mentor Qinglan Xia on Plateau-type problems and ways of generalizing the notion of iterated function systems.

I got my Mathematics PhD at Washington State University, where I was co-advised by Bala Krishnamoorthy and Kevin Vixie. During my PhD, I was an RA for Aurora Clark's computational chemistry lab. There, I applied geometric measure theory and TDA techniques to various types of chemical simulation datasets. Link to my CV (updated 11/07/25).

Research

I am a mathematician with a variety of pure and applied interests. I enjoy thinking about analysis, topology, and their applications to the physical and data sciences. Within mathematical analysis, I am interested in geometric minimization problems that you find within the area of geometric measure theory. For example, the Maximum Distance Problem [ACMN, AKV1] and a type of Partial Plateau's Problem [AX1]. I am interested in the various ways that one can generate fractals [AX2] and have recently been interested in fractional rectifiability. Within the area of applied topology, I am interested in parameter selection problems for Mapper [A_1, A_2], and questions which relate properties of sets to their random samples [AKV2].

I love interdisciplinary projects. I have collaborated with chemists, physicists, and data scientists -- writing code to apply the tools from above areas to help them solve problems they think are interesting. I combined tools from persistent homology and geometric measure theory to find interesting features on liquid-liquid interfaces [ALSKC] and was part of a large group that analyzed energy landscapes via sublevelset persistent homology [MZY_].

Teaching

Iowa State University

For the Fall 2024 semester, I am teaching a graduate course in Algebraic Topology. We are using Spanier's classic text on the subject.

University of California, Davis

At Davis, I mainly taught undergraduate analysis courses (MAT 127 A, B, and C). In the first two courses, we went through all of Abbott's Understanding Analysis textbook, and in the last course, C, we went through about half of Munkres' Analysis on Manifolds text. I absolutely loved teaching out of both of these textbooks. Here are my lecture notes for 127A, and my lecture notes for 127C in case you would like to take a look :)
I also taught an "Introduction to Proofs" class, Calculus II (honors), Vector Calculus, and Calculus for the Biosciences.

Washington State University

Throughout my time at WSU, I was a TA for the calculus series, I taught a class on probability, and a couple of other lower-division mathematics courses.

Mentorship

Undergraduate research was pivotal in my mathematical upbringing and helping undergraduate students (especially underrepresented students) find their mathematical curiosity and drive is a very important me. During my time at UC Davis, I lead a group of 3 undergraduates to investigate ways that one could program a computer to randomly sample shapes, and at Iowa State, Eric Weber and I are running an ISMaRT project for undergraduates investigating similar questions. In the Fall of 2024, Robin Belton and I lead a group of 2 undergraduates and 2 graduates in "Projects in TDA" to investigate questions related to parameter selection in Mapper.
