I am Jianqing Zhang, a second-year PhD student in Computer Science, co-supervised by Yang Liu at Tsinghua University and Jian Cao at Shanghai Jiao Tong University. I have also had the privilege of collaborating with Qiang Yang at HKUST, Zhenzhe Zheng at Shanghai Jiao Tong University, and Yang Hua at Queen's University Belfast. Previously, I worked at the Shanghai Key Laboratory of Scalable Computing and Systems and earned my Master's degree from Shanghai Jiao Tong University in 2023.

My research interests include Code LLM + RL, Evolutional Data Generation, and Federated Learning. I am also a passionate photographer, always seeking to capture the beauty of the world through my lens.

I am seeking research internships, visiting positions, and postdocs. Feel free to contact me if interested!
