About Me
I am Jiaqi Deng (邓嘉奇), an undergraduate student from Department of Computer Science, The University of Hong Kong. Currently, I am working as the research assistant of XLANG Lab, HKUNLP Group and intern of Moonshot AI. And I am fortunate to be advised by Dr. Tao Yu during my internship at XLANG Lab.
I am currently working on projects related to multimodal agents, especially computer-use agents. And I am trying to build autonomous, robust and generalizable agents via reinforcement learning. My long-term interest is to find the paradigm of building self-evolving agents. To achieve this, I have worked on projects related to improving agentic foundation models, agent data synthesis, agent evaluation, and etc.
I am actively seeking PhD opportunities starting in 2026 Fall, and if you are interested in my works, please feel free to contact me.
