Focused Experience

Graduate Research Assistant

Shipman Lab & Erraguntla Lab, Texas A&M

Jan 2024 – present
  • Performed K-fold cross-validation over an ensemble network (using VAE and 12-lead ECG spectrograms) achieving AUC > 90% for cardiovascular classification.
  • Utilized LIME analysis for explainability and engineered an LLM integration for doctor's notes, improving real-time multi-modal predictions.
  • Built an ECG-to-text model leveraging LLMs, trained on ~50,000 samples for automated text-based clinical interpretations.
  • Led ML research for a $1M FDA-funded project on infant Aortopulmonary Shunt occlusion, architecting an XGBoost ensemble scoring peak AUC 0.867.
  • Implemented a multi-layered XAI framework using SHAP to generate actionable clinical narratives for PICU teams.

Data Science Intern

Delfina

May 2025 – Sept 2025
  • Developed a Gradient Boosting Classifier predicting Gestational Weight Gain via clinical EHR and self-reported data across 4 clinics (AUC 0.85).
  • Engineered longitudinal weight trajectory features combined with multi-modal predictors such as BMI and parity.
  • Conducted rigorous bias/stability analysis utilizing DeLong’s test, proving model stability (p > 0.05) across diverse racial and BMI categories.

Graduate Research Assistant

Perception, Sensing, and Instrumentation Lab, Texas A&M

Sept 2021 – Dec 2023
