About Me

Here is Yifan Xie (Ivan, 谢奕凡).

I am currently a Ph.D. student in Data Science and Information Technology at Tsinghua University, supervised by Prof. Wenbo Ding. Previously, I obtained my Master’s degree in Software Engineering from Xi’an Jiaotong University in 2025.

My research focuses on MLLM, Embodied Intelligence and 3D Vision. Feel free to reach out for collaboration and discussion of research ideas (Email: ivanxie416[at]gmail.com).
