Aishwarya Mandyam

I am a Computer Science PhD candidate at Stanford University working with Barbara Engelhardt and Emma Brunskill. I'm interested in building statistical/ML tools to improve clinical decision-making.

Outside of research, I enjoy distance running, dogspotting, and eating black forest cake.
