We are pleased to announce that Assistant Professor Hanna Wallach and her students Meagan Day and Rachel Shorey are now part of the CIIR. Dr. Wallach joined the Computer Science Department in Fall 2010 as part of UMass Amherst's interdisciplinary research cluster in computational social science. Her primary research goal is to develop new mathematical models and computational tools for analyzing vast quantities of structured and unstructured data in order to identify and answer social science questions.
