About Me

Hi, I am from Carnegie Mellon University. Before that, I graduated from Tsinghua University. I have broad research interests in data mining and machine learning, especially their large-scale applications. Specifically, I am interested in developing more advanced machine learning and deep learning methods for information retrieval and large-scale distributed systems, from optimization and architecture perspectives. I was once a research intern at some big techs like Tiktok, improving the trillion-parameter models. I serve as the PC member for ICLR, AAAI, and TOIS. I used to participate in ACM-ICPC, which is a distant memory now.
