"Convince future generations, not just peers."


At the gorgeous Westlake, Hangzhou

Hi there 😃. I am Tongtian Zhu (prounced as “Tong-tee-an Joo”), a second-year PhD student at the Computer Science Department of Zhejiang University (ZJU), under the auspices of Professors Mingli Song and Chun Chen. I earned my B.S. degree in Mathematical Science from CUMTB, as well as my B.Econ. degree in Economics (double degree) from Peking University (PKU) in 2021. In the same year, I joined JD Explore Academy (JDE) as a a research intern, where I focused on the generalization theory of decentralized learning, fortunately supervised by Professors Fengxiang He and Dacheng Tao.

🦄 Research Interest

In the science aspect, my primary research interest lies in understanding the mechanisms underpining the practical success of deep learning. My ultimate goal is to understand the emergence of intelligence (both machine intelligence and biological intelligence). In the technology aspect, I am passionate about developing machine learning methodologies inspired by principles.

My current research focuses on examining the theoretical foundations of decentralized learning. I am also dedicated to utilizing elegant theoretical insights to construct fast and generalizable decentralized learning algorithms.

Please always feel free to contact (via email or WeChat) if you have any questions, are interested in collaborating, or simply want to chat. For regular updates and insights, feel free to follow my Twitter as well.
