Samantha Kleinberg has joined the Computer Science Department as an Assistant Professor. She received her PhD in Computer Science from New York University in 2010 and was a Computing Innovation Fellow at Columbia University in the Department of Biomedical informatics from 2010-2012. Her research centers on developing methods for analyzing large-scale, complex, time-series data. In particular, her work develops methods for finding causes and automatically generating explanations for events, which facilitate decision-making using massive datasets. She is particularly interested in applications to biomedical datasets from electronic health records and intensive care units. Her book Causality, Probability, and Time will be published by Cambridge University Press in November.
