About Me

I am a South Texas native originally from the border city of Laredo. I completed my Bachelor of Arts degree in Biology with a minor in Music Performance at Texas A&M International University. Throughout my undergraduate years, I actively participated in the symphonic band and the 'Mariachi Internacional' group. Additionally, I gained valuable experience as an academic tutor at the university learning center, where I assisted students with biology, math, and music theory classes. After graduating, I continued my educational journey at The University of Texas at San Antonio, where I obtained my Master of Science degree in Biology. My graduate thesis focused on the genomic and transcriptomic analysis of Shiga-toxin producing enterohemorrhagic Escherichia coli. Following my graduate studies, I spent a gap year in Dickinson, Texas, where I lived with my wife and worked as a medical scribe. Now, I am thrilled to be back in San Antonio as a trainee in the South Texas Medical Scientist Training Program.


I enjoy playing the trumpet, chess, video games, cooking and tasting new foods, and going for walks in the park.

Cancer Biology

Why I chose MD/PhD

By choosing to pursue a joint MD/PhD program, I sought to integrate my goal of becoming a physician who could help patients on an individual basis and my goal of becoming a medical researcher who could work to improve the quality of life for patients around the world. 

Why I chose MD/PhD at UT Health San Antonio

Ever since my first interview at UT Health San Antonio, the strength of the community between students in the program and the passion exhibited by program leadership have been immediately apparent. This, combined with the excellent faculty mentors and research opportunities on campus, made selecting this program for my MD/PhD training an easy choice.
