Greetings!

I am Jiong (煚), a Ph.D. student in Computer Science and Engineering at the University of Michigan working with Danai Koutra. My research interest is on Graph Neural Network (GNN). Currently, I am working on understanding and improving GNNs on graphs with complex properties, such as graphs which go beyond the traditional homophily assumption (i.e., where the linked nodes are similar) by showing heterophily.

I was a Master’s student in Electrical and Computer Engineering at UM. Before joining UM, I received my bachelor degree at Xi’an Jiaotong University, where I was a student of the Special Class for the Gifted Young.

Apart from my study, I am a savvy tech user and a go-to friend for coding and tech questions.
