👋 I am James Zhao, a third year PhD candidate of School of Computing at National University of Singapore. I am co-advised by Prof. Bryan Hooi and Prof. See-Kiong Ng. Before that, I obtained master’s degree and bachelor’s degree from NUS and UESTC respectively.

Recently, I am interested in test-time scaling and agentic search. I always welcome collaborations and discussions about these topics. If you’re interested, feel free to reach out! 😃
