Selected Work
AI & Engineering Case StudiesBrain Tumor Segmentation (U-Net)
Built a deep learning model to automate glioma segmentation in MRI scans. Benchmarked U-Net against SegNet, achieving 64.83% Dice Coefficient for improved diagnostic precision.
Healthcare Data Pipeline
Architected an ETL pipeline to ingest raw US healthcare claims. Standardized disparate sources into a unified schema using SQL and Python to enable downstream analytics.
Sentiment Analysis (BERT vs CNN)
Developed a sentiment classification system for business reviews. Fine-tuned BERT Transformers achieving 92% accuracy, outperforming traditional CNN models (85%).
Algorithmic Bias in LLM Code
Replicating and extending the "Bias Unveiled" paper. Developed a "Smart Combination Testing" framework that solved predicate masking, increasing bias detection by ~108% (559 to 1,164 cases) compared to the original baseline.
