About

I’m Juncheng, currently a master’s student at ECE, NUS, where I’m fortunate to be advised by Dr. Jiawei Du and Prof. Joey Tianyi Zhou. My research focuses on Data-centric AI, including dataset distillation, data-efficient optimization, and recently physical agentic engines and harness engineering (AgentOS).
