PEOPLE

WENBO ZHANG (PhD student - arriving Spring 2020)

Wenbo Zhang will be joining us in January 2020 as a first year PhD student in the College of Information Sciences and Technology at Penn State. He will be co-advised by Dr. Anna Squicciarini (College of IST). Wenbo holds a Master of Science degree from the University of Southern California and a Bachelor of Science from the University of Electronic Science and Technology of China. He is interested in machine learning, and applications of data science. 

SARAH RAJTMAJER (PI)

Sarah Rajtmajer is an assistant professor in the College of Information Sciences and Technology, core faculty in the Rock Ethics Institute, an. Before joining the Penn State faculty, she served as a consultant to the Defense Advanced Research Projects Agency (DARPA) and the Intelligence Advanced Research Projects Agency (IARPA) on scientific programs aimed at breakthrough technologies for national security, with specific focus on initiatives in big data and computational social science.  Prior to her work in consulting, Dr. Rajtmajer was an Intelligence Community Postdoctoral Research Fellow at the Applied Research Laboratory and a Postdoctoral Scholar in the Department of Mathematics at Penn State.
Dr. Rajtmajer’s research integrates graph theory, game theory, and machine learning, with applications to social and biological phenomena.  Recent work aims at characterization and modeling of behavior within evolving social networks both in the abstract as evolutionary games on structured populations, and in applied, data-driven scenarios related to privacy decision making, deviance, and abuse. Current focus includes implications of these behaviors for emerging topics in defense and intelligence. In addition, Dr. Rajtmajer is interested in understanding fundamental issues around credibility and reproducibility in big data science. In particular, the large datasets considered in computational social science bring additional challenges as privacy protection dovetails with the usual conversations around methods, reporting and dissemination standards, evaluation and incentives.  
Dr. Rajtmajer has a PhD in Mathematics from the University of Zagreb, Croatia, and a BA in Mathematics from Columbia University.

TAYLOR BLOSE (PhD student)

Taylor is a first year PhD student in the College of Information Sciences and Technology at Penn State. Prior to enrolling, Taylor was an Intelligence Analyst with the Federal Bureau of Investigation where he supported National Security and Criminal investigations while also aiding the growth of the FBI's geospatial intelligence program. Before joining the FBI, Taylor graduated from Penn State University with a Bachelor of Science in Security and Risk Analysis. Taylor is interested in researching social media use during crisis situations, trust in social media, and the vulnerabilities of such trust that may be exploited by malicious actors.
