Hello! Currently, I’m a visiting student researcher at Allen Institute for AI, fortunate to be hosted by Youngjae Yu, Jack Hessel, and advised by Yejin Choi.

My goal is to build AI systems that collaborate with people to make decisions when solving real-world problems, including scientific research, education, and mental health support. To achieve this mission, I am particularly interested in enhancing AI systems to be more user-friendly as I firmly believe the technology should focus on people using AI systems. Methodologically, my recent interest lies in scalable methods, including learning without human supervision (weakly supervised learning ‚ÄĒ CHAMPAGNE), learning through interaction, and evaluating models with the assistance of other AI models (building a benchmark ‚ÄĒ NormLens).

Previously, I worked on research and engineering at Hyperconnect (acquired by Match Group for $1.7B), solving product-related problems (PC Softmax & LADE) and build social chatbot product (DRESS, PDP, CORGE, G2R, Attentron) to solve people’s loneliness.

I like workouts in the gym and singing music. p.s. I participated in building a product (GYMWORK) to assist people with their workout routines!
