Our Leadership Team

Dr. Timothy Huber received his Masters degree in Mathematics from Northern Illinois University in 2001 and PhD from the University of Illinois at Urbana Champaign in 2007. He is currently an associate professor and Director for the School of Mathematics and Statistical Sciences at The University of Texas Rio Grande Valley. Timothy is involved in a variety of initiatives to engage and empower students, with a particular emphasis on connecting students with research programs early in their careers. His research interests include analytic number theory, combinatorics, special functions, and elliptic modular forms.

Dr. Hyung Kim is an Associate Professor of Math Education in the School of Mathematical and Statistical Sciences at the University of Texas Rio Grande Valley. He received his PhD in 2013 from the University of New Hampshire in Math Education. At UTRGV, he has taught various math courses for preservice math teachers and math education courses for graduate students, most of whom are in-service teachers of mathematics. His primary research interests are mathematics teachers’ development of teacher identity and statistics teaching and learning.

Karina Araiza has been a mathematics educator for more than fourteen years. She supports our local Rio Grande Valley Math Teacher's Circle because she believes everyone is a natural born mathematician and that the aesthetics of the mathematics art is worthy to be shared with and by all students, regardless of their age. As part of her teaching philosophy, she enjoys conveying the following antithesis to her students, mathematics is as simple as wishing for something and making it happen and as complex as the language that holds the answers to all questions in our universe. When she is not in school, she spends the most possible time with her family.

Ana Castillo is in her 8th year teaching. She teaches 9th grade Algebra I at Raymondville Early College High School. She strongly supports inquiry based learning and believes that is the best way for students to learn mathematics. She has been a past participant of the Park City Mathematics Institute Teacher Leadership Program (PCMI TLP) in 2018 and coordinated a PCMI TLP weekend local workshop in February 2019. In her spare time, she enjoys the outdoors, spending time with pets, shopping, traveling, cooking, karaoke, reading, and writing.
