Welcome! I am a third-year Ph.D. in Binghamton University (BU). My research focuses on human-centered AI, machine learning, natural language processing, computational social science, and conversational AI.

I am interested in understanding psychological and cognitive states as reflected in human language interaction. Specially, my PhD study focuses on Trust Dynamics in Human-AI Communication. My study goals is to advance trustworthy, adaptive AI system by (1) capturing, visualizing and modeling trust dynamics, and (2) developing real-time trust-adaptive conversational agents in individual and group settings. Three mentors support my study from different displines: Dr. Sadamori Kojaku (machine learning and data visualization) at BU, Dr. William Hayes (computational cognitive modeling) at BU, and Dr. Min Sun Kim (communication and social influence) at University of Hawaii at Manoa. My study is funded by Multidisciplinary Summer Research Grant from the Center for Cognitive Applications, BU and Professor Jim Geer Summer Scholarship launched by Dr. Nana Banerjee. My study on trust has been highlighted on Communications of the ACM, The Science Archive, TechXplore and BingUNews.

In Summer 2023, I was summer research intern at the Research Foundation at SUNY and contributed to Community Energy Compass - Data-driven Visualization Toolkit Development (Under the supervision with Dr. Neha Patankar and collaborating with Zero Lab held by Dr. Jesse Jenkins at Princeton University).

Now I am actively seeking Research Internship. Please feel free to contact me if you think I match with any position that you provide or want to recommend to me. Email: xinwang35314@gmail.com
