OverviewAI-generated summary
Paul M. Gignac's research focuses on the application of advanced imaging techniques, particularly three-dimensional computed tomography (3D CT), to investigate the evolutionary biology and functional morphology of vertebrates. His work often involves the use of diffusible iodine-based contrast-enhanced computed tomography (DiCE-CT) to reconstruct and analyze soft tissue structures, such as brains and musculature, in a variety of species, including birds, reptiles, and mammals.
Gignac has published research examining neuroanatomical integration and scaling in avian brain shape evolution, the phylogenetics and evolution of terrestriality in mudskippers, and the cranial musculoskeletal description of finches using DiCE-CT. He also investigates comparative digital reconstructions of bird skulls and their cranial suture ontogenies, as well as functional imaging of the pigeon brain in relation to powered flight evolution.
His scholarship metrics include an h-index of 23 and over 2,420 citations across 89 publications. He is designated as a high-impact researcher and collaborates with researchers from institutions including Arkansas State University and the University of Arkansas at Fayetteville.
