About Me

I'm a medical student at the David Geffen School of Medicine at UCLA with a background in computer science and neurobiology from UC Irvine, where I graduated Phi Beta Kappa and Magna Cum Laude.

Previously, I spent 4+ years in UC Irvine's BCI Lab where I designed custom PCBs, built real-time neural signal visualization software, and engineered hardware for a brain-controlled walking exoskeleton. That work earned First Place at the IEEE EMBC Young Professional Paper Competition and contributed to 7 publications.

Now I'm focused on health tech — I co-founded Transcend Medical, a startup connecting patients with gender-affirming care providers, and Teddy Bear Hospital USA, a non-profit expanded to 7 university chapters. I build tools that bridge technology and healthcare — one project at a time.

Projects

Stroke Localizer

Stroke Localizer

An interactive web app for medical trainees to practice neurological stroke localization. Select symptoms or type a clinical description — the app uses rule-based logic and AI to identify the affected vascular territory, visualized on an interactive 3D brain model and Circle of Willis diagram.

Key Features

  • 45 symptoms across 7 neurological exam categories
  • 31 localization rules covering 13 vascular territories
  • AI-powered free text parsing with Claude
  • Interactive 3D brain with React Three Fiber
  • Multi-plane 2D SVG views (axial, coronal, sagittal)
  • Circle of Willis artery diagram with occlusion markers
  • Bidirectional hover interactions between results and visualizations
  • Step-by-step clinical reasoning explanations

Transcend Medical

As Co-Founder & CTO, I'm leading the development of a mobile platform that helps patients find vetted, gender-affirming care providers. The app features real-time messaging, appointment scheduling, provider search with filtering, and a review system — all designed with accessibility and trust at the core. Currently in beta testing at UCLA.

Key Features

  • Real-time messaging between patients and providers
  • Appointment scheduling system
  • Provider search with filtering and reviews
  • Provider onboarding, verification, and customizable profiles
  • Beta tested at UCLA with iterative user feedback
  • Cross-functional collaboration with clinical advisors
