Please join us in congratulating Associate Professor Sifan Xu, the newest DeForrest Jackson Professor in the Tombras School of Advertising and Public Relations!
Established through a generous gift from Suzanne Sackleh ('89) in honor of her favorite professor, DeForrest Jackson, this prestigious professorship recognizes a faculty member whose research, teaching, and service make an exceptional impact on the Tombras School, UT College of Communication & Information, and University of Tennessee, Knoxville.
Over the next three years, Associate Professor Xu will use the professorship to further an active research agenda, which explores the role of artificial intelligence, specifically Large Language Models (LLMs) and AI-powered conversational chatbots, in transforming crisis communication from mass-broadcast
risk messaging into adaptive, personalized risk education.
He will focus on producing impactful scholarship while helping elevate the Tombras School’s visibility on the national and international stage.
