Frontotemporal Dementia Research

Making machine-aided diagnosis explainable to doctors.

Frontotemporal dementia, a specific type of dementia, is extremely hard for doctors to diagnose. A highly accurate model means little if doctors cannot interpret or trust its decisions. Under the guidance of Dr. Shihab Shamma and Maryam Shaghaghi at UMD, I built a system that highlights abnormal brain activity behind each prediction. Instead of a black box, doctors can see why the model made its decision.

For this research, I was recognized by Regeneron Pharmaceuticals as a STS Top 300 Scholar.

Brain activity recordings

Raw brain activity recorded from patients is messy and noisy. Each line is electrical signals from a different part of the brain.

I worked on a pipeline that transformed raw brain signals into measurable features across regions and frequency bands, then visualized how frontotemporal dementia patients differ from healthy controls.
