CoQuest's live campus map showing quest pins near Stanford landmarks2025

CoQuest — Spontaneous Social Coordination

A full-stack React Native + Firebase app that lets students broadcast and join spontaneous hangouts in real time — live in a 3-day pilot, 10 users generated 67 quests.

  • TypeScript
  • Firebase Authentication
  • Firestore
Bar chart comparing peak GPU memory usage across fine-tuning methods on SST2025

Parameter-Efficient Adaptation of GPT-2

Built a GPT-2 Transformer from scratch and benchmarked parameter-efficient adaptation methods (LoRA, ReFT, soft prompts) against full fine-tuning — ReFT matched or beat full fine-tuning accuracy using 0.02% of the trainable parameters.

  • Python
  • PyTorch
  • Transformers
  • GPT-2
Pipeline from 3D patient model to virtual stent placement to CFD pressure simulation, with a before/after pressure comparison2026

Virtual Stenting in the Fontan Circulation

A patient-specific computational pipeline — 3D modeling, mesh generation, and CFD simulation — quantifying how virtual stent placement changes cardiovascular hemodynamics at rest and during exercise.

  • SimVascular
  • svMorph
  • Computational Fluid Dynamics
  • 4D Flow MRI
Illustration of the E-PVO probe positioned transesophageally near the left atrium and pulmonary veins, with a sample oxygen-saturation readout2026

Neonatal Photoacoustic Oximeter

A miniaturized transesophageal photoacoustic sensor developed across four staged milestones to estimate pulmonary venous oxygen saturation in neonates with congenital heart disease.

The assembled benchtop centrifuge prototype with its LCD control display reading "Press Start To Begin"2024

Custom Benchtop Centrifuge

Built a benchtop centrifuge from scratch — fabricated rotor and enclosure, Arduino motor control, optical RPM sensing, and phase-aware visual and auditory feedback so operators can safely step away during long runs.
