Hello! I’m Chen Ju (鞠陈).

I’m an algorithm researcher of Alibaba Search and Recommendation Department, working closely with Dr. Weilin Huang, Dr. Shuai Xiao, Dr. Xu Chen, and Dr. Zhonghua Zhai. The vision is to develop large-scale visual searching system (拍立淘) and general multi-modal technologies for various e-commerce applications, such as superlarge-scale pre-training (10-billion image-text product data), AIGC (GPT & VLM & Diffusion). Now it has become one of the largest visual/multi-modal application scenarios in China.

Recently, I study with some outstanding researchers from the CAD&CG State Key Laboratory, Zhejiang University: Prof. Chunhua Shen, Prof. Hao Chen, and Prof. Bohan Zhuang, aiming to explore the efficient/unified architecture and paradigm for next-generation VLM.

I’m also leading one small group that mainly works on Efficient Data Understanding & Generation for Multi-Modal Foundation Models(Data Flywheel/Governance, Advanced Paradigm/Framework, Creative AIGC). Actively recruiting research/engineering interns, please see Link, feel free to contact me!

Before that, I explore with some outstanding researchers from WeChat Technology (微信技术架构), Tencent: Dr. Fengyun Rao, Dr. Yizhou Zhou, Dr. Guangting Wang and Dr. Yukun Su, working to develop chinese pre-trainings of image-text-video-music, namely WeMM, WeCLIP, WeMU.

Earlier, I collaborate with some outstanding researchers from PanGu Large Model (盘古大模型), Huawei: Prof. Qi Tian, Dr. Lingxi Xie, Dr. Xiaopeng Zhang, Dr. Jianlong Chang, Dr. Jiemin Fang, and Dr. Peisen Zhao, to explore VLM for B-side industrial scenarios.

I obtained the PhD’s degree from MediaBrain Group, Shanghai Jiao Tong University, advised by Prof. Yanfeng Wang (人工智能学院院长) and Prof. Ya Zhang (国家万人), also collaborating with Prof. Weidi Xie(海外优青), Prof. Siheng Chen(海外优青), Prof. Yu Wang and Prof. Jiangchao Yao. Before, I obtained a Bachelor’s degree in Engineering from University of Electronic Science and Technology of China, where I studied under Prof. Yong Liu (国家杰青 & 长江学者), awarded with the honor of outstanding graduate.
