Stephen J. Hagen is a Professor and Chair of the Physics Department at the University of Florida, affiliated with the College of Liberal Arts and Sciences. His research focuses on the dynamics of biological systems, particularly protein folding mechanisms and bacterial quorum sensing networks. He holds a Ph.D. in Physics from Princeton University (1989) and a B.A. in Physics from Wesleyan University (1984).
His work integrates biophysics, microbiology, and systems biology to study how bacteria communicate and respond to environmental cues. Notable areas include quorum sensing in Vibrio fischeri and Streptococcus mutans, protein folding dynamics using laser spectroscopy, and the role of noise in gene regulatory networks. He has advised numerous graduate students and postdoctoral researchers, with a lab focused on interdisciplinary approaches to biological physics.
Publications highlight advancements in understanding bacterial communication, biofilm formation, and protein behavior. His lab uses microfluidic devices and advanced imaging techniques to study single-cell behavior, revealing insights into signal crosstalk and environmental adaptation. Collaborative efforts bridge physics, engineering, and microbiology to address questions in systems biology and biophysics.
