About Me

Shu Liu is a Ph.D. candidate majoring in Systems Innovation at the Graduate School of Engineering, The University of Tokyo, supervised by Prof. Fujio Toriumi.
His research interest is structural information mining in Complex Networks.
His work focuses on developing structure-based embedding methods for various types of networks, including signed networks, directed networks, weighted networks, and hypernetworks.
He is also interested in applying these methods to practical applications.
He currently serves on the steering committee for the Network Science Study Group
