About

I build low-cost wearable sensing systems and machine-learning pipelines for real-world health monitoring. I’m especially interested in gait and mobility, where signal processing and human-centered design can enable preventive tools and practical interventions outside the lab.

I care about technology that is useful and inclusive—open-source when possible, and designed around real constraints.

Research Interests

  • Wearables: sensing and embedded systems, low-cost instrumentation, and reliability in everyday environments.
  • Digital Health: mobility and gait monitoring, usability and adherence as research constraints, and deployable evaluation.
  • Machine Learning: clustering, personalization (profiles), interpretability.

Beyond the Lab

A curated view of what shapes how I work: curiosity, communication, design, and perspective.

Curiosity & Computational Thinking

Reading and curiosity
Reading & learning across topics

I read daily across science, history, culture, and technology. That habit fuels my research questions and helps me connect ideas across domains.

Grace Hopper, applications, Canal Once
Programming

Programming is more than work for me—it’s a creative outlet for prototyping ideas and turning questions into systems that generate data. I’m especially drawn to projects where the pipeline matters as much as the model (sensing, signals, visualization, deployment).

I admire people and media that make technology more human. Stories about figures like Grace Hopper. Since I was a child, Canal Once—a free public channel run by a university in Mexico City—was a major source of inspiration for me. Its children’s educational programs were creative, clear, and deeply inspiring, and they sparked my interest in learning and sharing knowledge from an early age.

Rubik’s Cube
Rubik’s Cube

Speedcubing is my tangible way of thinking about algorithms—patterns, heuristics, and optimization under constraints. My personal best is around 19 seconds, and I like how it turns abstraction into practice.

Communication & Storytelling

Poetry
Multilingual poetry

Poetry taught me precision: choosing words the way you choose variables, with meaning and intent. Writing in multiple languages helps me communicate the same idea to different audiences with clarity.

Cinematography
Cinematography

I enjoy analyzing how framing, sound, and silence shape perception and emotion. It’s a fun way to think about attention. I particularly enjoy horror films.

Design & Self-Expression

Style and cosplay
Style as design practice

Clothing is one of my main forms of expression—color, texture, and silhouette are a kind of everyday design language. Small visual choices communicate mood and identity.

Modeling
Presence & confidence

Taking modeling classes pushed me outside my comfort zone and helped me develop confidence and presence. It made me more comfortable presenting ideas, receiving feedback, and showing up in new environments.

Culture, Identity & Grounding

Mexico City
Mexico City

Mexico City inspires me with its layered history, museums, and neighborhoods—it feels like walking through multiple eras at once.

Northern Mexico / Sinaloa

Being away from home made me value the culture I grew up with—music, accents, food, and everyday habits—in a deeper way.

Running Half marathon
Running

Running clears my mind and builds long-term consistency. I like it because progress comes from patience and iteration.

Dogs
Dogs

Dogs keep me grounded and make ordinary days better. They’re my reminder to stay present and human in the middle of ambitious goals.
