Megan K. Freiler studies how hormones and the brain shape animal communication and behavior, focusing on species like weakly electric fishes and gray treefrogs. Her work examines the biological mechanisms—such as steroid hormones (testosterone and estradiol) and brain energy demands—that underlie mating signals, social behavior, and the evolution of communication. She combines behavioral experiments with studies of neuroendocrine (brain-hormone) systems and gene expression.
Publication activity has been steady with a modest recent increase, averaging about 1.6 papers per year over the last five years.
