I am an Assistant Professor in the Department of Information Science at Drexel's College of Computing and Informatics. In my research, I focus on the intersection of Computational Social Science and Natural Language Processing (NLP) in order to gain a deeper understanding of human behavior, attitudes, and cultures through the analysis of text. By integrating computational models with social science theories, my goal is to develop NLP models that are both technically advanced and "socially-aware", taking into account the rich cultural and social context in which language is used. This allows for a more comprehensive capture of attributes such as social identities, stances, morals, and power dynamics from language, ultimately improving our understanding of real-world communication.
One of the most intriguing aspects of this field is the opportunity to study communication in online communities and social media platforms, where language is increasingly used to shape public opinion. I am particularly interested in using various models to study communication in these contexts, where language conveys complex social and cultural information. My current research topics include:
Discourse analysis of substance use disorder on social media
Analysis of polarized viewpoints on social media
Investigating the long-term impact of information products on people and societies
Analysis of moral perceptions and viewpoints through user-generated texts and images
Text summarization (e.g., scientific articles)
Structural balance and stability in social networks
Linguistic properties of online social movements
I received my Ph.D. in Information Sciences from University of Illinois at Urbana-Champaign (UIUC) where I was advised by Dr. Jana Diesner.
I’m actively recruiting highly motivated students who are excited about working at the intersection of Computational Social Science, Natural Language Processing, Network Analysis, and Machine Learning. Students with both social and computational perspectives are particularly encouraged to apply. Find more details and instructions here.
