I am an Assistant Professor in the College of Software, Nankai University (NKU). Prior to that, I received my Ph.D degree at the Chinese University of Hong Kong in 2025, supervised by Prof. Michael R. Lyu. I obtained my Bachelor’s degree from Huazhong University of Science and Technology in 2021. My research focuses on reliability engineering in cloud systems based on observability data, especially performance monitoring metrics.

Please feel free to drop me an email if you are interested in my research topics.
