Hanna M. Wallach

Assistant Professor


In fall 2010, Hanna Wallach started as an assistant professor in the School of Computer Science at the University of Massachusetts Amherst. She is one of five core faculty members involved in UMass's new Computational Social Science Initiative. Prior to this, Hanna was a senior postdoctoral research associate, also at UMass, where she developed statistical machine learning techniques for analyzing complex data regarding communication and collaboration within scientific and technological innovation communities. Hanna's Ph.D. work, undertaken at the University of Cambridge, introduced new methods for statistically modeling text using structured topic models—models that automatically infer semantic information from unstructured text and information about document structure, ranging from sentence structure to inter-document relationships.
