Pengxiang Ding 丁鹏翔

Hi! I am Pengxiang Ding (丁鹏翔 in Chinese). I am a first-year Ph.D. student at Zhejiang University, advised by Prof. Donglin Wang. Additionally, I am involved in a joint program with Westlake University as a member of Machine Intelligence Laboratory (MiLAB). Prior to my Ph.D. career, I received my Msc. Degree from School of Artificial Intelligence, Beijing University of Posts and Telecommunications in 2022.

Research Interests

Currently, My research has centered on multi-modal large models (mainly on vision-language models), including

  • Multi-modal large models: multimodal large language models (MLLM), vision-language pre-trained models (VLM)
  • Embodied AI: foundation models for robotics
  • AIGC: human motion analysis

I am always looking for related collaborations, and some of them have produced top-level publications. If you are interested in communication, feel free to drop me an email.

News

  • [March 21, 2024] A new paper about Cobra, an efficient multi-modal large language model, was released. Project page has been available. The paper has been featured by Hugging Face Daily Papers! Demo has been available!
  • [December 9, 2023] One paper about whole-body human motion prediction got accepted for AAAI 2024.

Hiring: We are looking for postdoctors, research assistants and visiting students for MiLAB in Westlake University. More information about requirements can be found here, and if you are still in school, being a visiting student is also welcome. Please send email to mi_lab[AT]westlake.edu.cn with your CV if you are interested. Specially, if you are interested in my research direction and would like to be my collaborator after coming, please specify in the email and also send a copy to me.
