Xiaohan Zhao

I am a fifth-year PhD student in the Department of Computer Science at UC Santa Barbara. I work in the SAND Laboratory under the supervision of Professor Ben Y. Zhao.

I focus on analyzing and modeling both static graph topologies and dynamic graph evolution. I design fast and effecient embedding systems, (e.g. Rigel), to analyze massive social graphs. Rigel is used by Renren, Zynga, Google. My work also builds graph evolution models based on measured dynamic properties in online social networks.
