About Me

Hi! I am currently a Ph.D. student in College of Intelligence and Computing at Tianjin University, advised by Prof. Ce Yu, and at the Ludwig-Maximilians-Universität München (LMU) advised by Prof. Daniel Grün . I received my B.E. degree from Hebei University of Technology in 2020. From 2019 to 2020, I attended a joint training study program at Massey University and received my second Bachelor’s degree.

My current research lies at the intersection of computer science and time-domain astronomical problems– with a special focus on building intelligent and efficient scheduling methods for distributed telescope arrays for optical time-domain observations. My research interests include resource allocation and optimization, astronomical informatics, artificial intelligence, and high performance computing.

I am currently on the 2024-2025 academic job market, looking for faculty positions in computer science, astronomical informatics, management operational research etc., related to artificial intelligence, task scheduling, and time-domian astronomy. Please feel free to contact me if you are interested in any aspect, I would love to chat and collaborate, please email me at- zyj0928[at]tju[dot]edu[dot]cn
