Principal Investigator

Yu-Ru Lin

Associate Professor at the School of Computing and Information, University of Pittsburgh. She is a computer scientist by training, with research interests include data science, visualization, and computational social science. She has worked extensively on computational methodologies for mining, analyzing and visualizing large-scale, time-varying, heterogeneous, multi-relational, and semi-structured data. Her current research focuses on tracking and modeling collective behavior from big data sets, including data from social media and sensing technologies, for understanding human and social dynamics, particularly under exogenous events including disasters.


Rebecca Hwa

Associate Professor in the Department of Computer Science at the School of Computing and Information, University of Pittsburgh. Her recent research focuses on understanding persuasion from a computational linguistics perspective. Some of her recent projects include: modeling student behaviors in revising argumentative essays, identifying symbolisms in visual rhetorics, and understanding idiomatic expressions. Dr Hwa is a recipient of the NSF CAREER Award. Her work has also been supported by NIH and DARPA.

Wen-Ting Chung

Research assistant professor at the University of Pittsburgh. Her primary interests include how individual beings negotiate and transform the self and boundaries with others, while facing cultural transitions, societal reforms, and unexpected life happenings. She is an Educational psychologist by training; methodologically, she enjoys transdisciplinary approach, uses both qualitative and quantitative methods, but is mostly interested in discourse and narrative analysis.
