Aishwarya Mandyam

I am a Computer Science PhD candidate at Stanford University working with Barbara Engelhardt and Emma Brunskill. I'm broadly interested in building tools for decision-making within healthcare settings. I've focused on reinforcement learning algorithms, and have a particular recent interest in policy evaluation.

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

NeurIPS (Unofficial) Run Club

Are you attending NeurIPS 2024? Do you enjoy running? Join me (and several others) for the unofficial NeurIPS Run Club! We will run at a conversational (10:00-10:30 min/mile) pace. All runs will start from the Vancouver Convention Center and begin at 7:30 AM.

These are the planned routes. Join for however long you would like! All runs will be followed by coffee/breakfast at a local shop. If you're interested in joining, send me a note- we'll wait for you!

12/12/2024: Route (6.38 miles)

12/13/2024: Route (6.9 miles)

12/14/2024: Route (5.4 miles)

12/15/2024: Route (7.15 miles)
