Welcome to my homepage! I am Hyesun Choung, Assistant Professor in the Brian Lamb School of Communication at Purdue University. I study how people perceive, trust, and interact with artificial intelligence (AI) and other emerging technologies. My research examines the psychological, social, and ethical factors that shape trust in AI, with the goal of informing the design of transparent, fair, and human-centered technologies.

Although my research spans a range of contexts, I am especially interested in how AI shapes human judgment, communication, and well-being. More recently, I have explored how people use AI to seek and evaluate health information, how older adults interact with conversational AI, and how these technologies might help strengthen social connectedness and support psychological well-being.

My work has appeared in journals including Computers in Human Behavior, International Journal of Human-Computer Interaction, Public Understanding of Science, and Health Communication. Across these projects, I seek to advance both theory and practice by generating evidence that supports the development of trustworthy, responsible, and human-centered AI.

Thank you for visiting my site, and I invite you to explore my publications and ongoing projects!
