Wuhan University PhD, School of Computer Science, Wuhan University

I am Yaqi Xia, I am currently working toward the Ph.D. degree in computer science with Wuhan University under the supervision of Prof. Dazhao Cheng. My research interests include distributed deep learning model training, high-performance computing, and graph neural network (GNN) optimization. Before pursuing my Ph.D., I obtained both my Bachelor's and Master's degrees from Xidian University, where I had the privilege of being mentored by Prof. Rui Song. During this time, I laid the foundation for my research in computer vision, focusing on areas such as point cloud completion and remote sensing, which has significantly shaped my current academic trajectory.
