Austin R. Benson
I'm a postdoc at Cornell University in the Department of Computer Science. In July 2018, I will start as an assistant professor in the department.
My research develops computational frameworks for analyzing largescale and complex datasets coming from the Web, social networks, biology, and other scientific domains. This involves a combination of network science, matrix and tensor computations, data mining, machine learning, algorithm design, and highperformance computing.
