James W. Pennebaker, PhD (University of Texas at Austin) is the Regents Professor and Chair of the Department of Psychology at the University of Texas at Austin. Much of Dr. Pennebaker’s research focuses on the links among natural language, emotional upheavals, and health. Whereas his earlier work examined how writing about traumatic experience can improve physical health and immune function, his more recent studies have explored natural language. He finds that low-level word use is related to personality, deception, status, group dynamics, and emotional states. The author and editor of ten books and more than 250 scientific articles, Dr. Pennebaker is among the most cited scientists in psychology and psychiatry. His current work is funded by NSF and the Army Research Institute.
