OverviewAI-generated summary
Paul M. Gignac's research program focuses on the application of advanced imaging techniques to study the anatomy, evolution, and biomechanics of vertebrates, particularly extinct archosaurs and extant crocodilians. He has developed and refined methods for using diffusible iodine-based contrast-enhanced computed tomography (diceCT) to achieve high-resolution, three-dimensional imaging of soft tissues, a technique detailed in his 2016 publication.
His work also investigates the evolutionary patterns of avian brain size and shape, examining the utility of endocasts as proxies for brain morphology in birds and their dinosaurian relatives. Gignac has explored the biomechanical underpinnings of feeding strategies in extinct and extant animals, including bite force and tooth pressure experiments on crocodilians and the osteophagy of Tyrannosaurus rex. Additionally, his research has examined changes in the inner ear sensory systems of extinct crocodylomorphs during their transition from terrestrial to aquatic environments.
Gignac leads a research group at the University of Arkansas at Fayetteville and has a notable publication record with 87 total publications and over 2,500 citations, contributing to his h-index of 23. He has established collaborations with researchers from Arkansas State University and the Arkansas Agricultural Experiment Station.
