Hello! I am Qingyu Guo (郭庆宇), a Ph.D. candidate from Hong Kong University of Science and Technology. I am honored to be advised by Prof. Xiaojuan Ma since 2019.

My research interest lies in social computing and Human-Computer Interaction (HCI), with a focus on the topic of online creativity communities. Additionally, I have explored leveraging technology for social good, such as online social support and education.

Besides my supervisor, I am fortunate to have the opportunity of conducting research with Prof. Hao Liu, Prof. Fuzhen Zhuang, and Prof. Hui Xiong between 2019 and 2020 at Baidu Research. Under their guidance, I have been working on the topic of time-series forecasting and the application of graphs.
