ABOUT ME

I'm a PhD researcher specializing in the intersection of artificial intelligence and biomedical engineering. My work focuses on developing multi-modal AI systems for early disease detection, particularly in Parkinson's Disease screening using advanced machine learning techniques.

With expertise in deep learning, computer vision, signal processing, and full-stack development, I build end-to-end AI solutions that make a real impact in healthcare and beyond.

FEATURED PROJECTS

ViT-KNN Parkinson's Detection

Published 2024
96.77% Accuracy
PyTorch Vision Transformer KNN scikit-learn

Hybrid Vision Transformer + KNN model for Parkinson's Disease detection from spiral drawings. A key architectural insight: augmentation strategies must be architecture-aware. The model performs best on original, unaugmented data, challenging common assumptions in medical AI.
