Yichen Wei

I graduated from Brown University in 2025 with a Master of Science in Computer Science. I am currently a research assistant at Brown Intelligent Robot Lab and Human To Robots lab, advised by Professor George Konidaris, Professor Stefanie Tellex, and Professor James Tompkin.

I aspire to build general, intelligent robots that seamlessly perform everyday tasks—from cooking meals to cleaning rooms. My current research interests center on enabling robust long-horizon decision making through neuro-symbolic methods, and designing intuitive human-robot interaction interfaces.

Outside of research, I enjoy cooking, traveling, and photography.
