Todd Freeberg, a Biology professor at the University of Tennessee - Knoxville, is a leading researcher in animal vocal communication within the Department of Psychology, holding an adjunct appointment in the Department of Ecology and Evolutionary Biology. He directs the Comparative Communication Lab, which studies how social processes influence vocal signaling in birds, including Carolina chickadees and tufted titmice. Freeberg obtained his Ph.D. in Biology from Indiana University in 1997. He conducted postdoctoral research in the Department of Audiology and Speech Sciences at Purdue University prior to joining the University of Tennessee in 2008 as Assistant Professor in Psychology. He advanced to Associate Professor, serving until 2015, and then to Professor. In administrative roles, he serves as Director of the College Scholars Honors Program, Associate Head of the Psychology Department, and Experimental Program Director.
Freeberg's research interests encompass the relationships between social complexity and communicative complexity, acoustic sequences in non-human animals, and the effects of group size and social dynamics on vocal information content and usage. His key publications include "Social complexity as a proximate and ultimate factor in communicative complexity" (2012), "Acoustic sequences in non-human animals: a tutorial review and prospectus" (2016), "Social complexity can drive vocal complexity: group size influences vocal information in Carolina chickadees" (2006), "Perspectives–minimizing observer bias in behavioral studies: a review and recommendations" (2012), "Linking social complexity and vocal complexity: a parid perspective" (2012), "Animal vocal sequences: not the Markov chains we thought they were" (2014), and "Chick-a-dee call variation in Carolina chickadees and recruiting flockmates to food" (2009). These contributions have shaped advancements in animal behavior, comparative psychology, and behavioral ecology.
Freeberg has received the 2009 University of Tennessee Department of Psychology Faculty Appreciation Award for Graduate Teaching and Research, the 2011 Fulbright Award to teach in Latvia, and the 2017 University of Tennessee Chancellor's Award for Research and Creative Achievement. His scholarly impact is reflected in the high citation counts of his publications.
