I am Kanzhi Cheng (程瞰之), a PhD student (2021.9 - ) in the NLP Group at Nanjing University, advised by Dr. Jiajun Chen & Dr. Jianbing Zhang. Previously, I worked as a research intern at Shanghai AI Lab, Tsinghua AIR, and Microsoft Research. I am deeply grateful for the opportunity to work with and learn from Dr. Zhiyong Wu , Dr. Hao Zhou, and Dr. Qianhui Wu.

Currently, I am broadly interested in multimodal intelligence, with a focus on:

• (Multimodal) Autonomous Agents: particularly GUI agents capable of acting in the digital world to automate complex tasks (SeeClick, OS-Atlas, OS-Genesis, GUI-Actor).
• Large Vision-Language Models: building multimodal systems that can understand image/video, generate text (Beyond Generic, CapArena), and perform reasoning (MM-Self-Improve).

I expect to graduate in 2026. Please feel free to reach out!
