I study why people responddifferently to exercise.

At Stanford, I connect physiological measurements from patients and athletes with molecular data from MoTrPAC.

Research

What I am working on now.

The work below reflects my current Stanford collaborations and outside sports-science partnerships.

01NIH consortium

MoTrPAC

A bout of exercise triggers different molecular responses in blood, muscle, and adipose tissue. In MoTrPAC, I connect those measurements with clinical exercise tests.

Multi-omicsClinical phenotyping
02Athlete performance

High-performance sport

With Stanford Baseball and outside sports-science teams, I study how athletes adapt to training. Recent projects have tested resisted sprints and video-based jump assessment.

Performance testingAthlete monitoring
03Integrated physiology

Cardiopulmonary exercise testing

For the MoTrPAC CPET core lab, I work on data quality and threshold determination. I also build the software used to review test results.

Quality controlThresholds
04Sports cardiology

ECG and sports cardiology

Large digital ECG datasets let us test screening criteria in female and male athletes from different racial groups. At Stanford, I study repolarization and sex-specific thresholds.

Athlete ECGScreening criteria
05Clinical exercise physiology

Clinical populations

In neuromuscular disease and limited mobility, recovery measurements can be more informative than peak-exercise values. A separate project measures carotid blood flow and shear stress, vascular signals relevant to stroke risk.

Neuromuscular diseaseExercise recovery
06Digital research

AI agents and apps

I build research agents and teaching apps when a recurring problem needs its own tool. Current collaborations include video-based movement assessment and language-model coaching for physical activity.

Education and training

Training in exercise physiology, biomechanics, and bioinformatics.

I trained in kinesiology, clinical exercise physiology, and biomechanics at the University of Texas at El Paso. At Stanford, my postdoctoral work has focused on human performance, myocardial biology, and bioinformatics.

About

I study exercise in clinical, laboratory, and performance settings.

I trained at the University of Texas at El Paso from my bachelor's degree through a doctorate in interdisciplinary health science.

I came to Stanford in 2022 through the Wu Tsai Human Performance Alliance and joined Cardiovascular Medicine in 2024. My current work also connects with the Stanford Bioinformatics Core.

As a Mexican American scientist with Indigenous heritage, I care deeply about mentorship. I build teaching tools because exercise science should be easier to learn and use.
