Florida-raised fish biologist who chases questions about form and function everywhere from the deep ocean and rocky tide pools to flooded savannas and roaring tepui rapids. He blends fieldwork, anatomy, and biomechanics to figure out why animals look and perform the way they do. When not dissecting skulls or scanning specimens, he’s probably somewhere getting his boots wet (again).
Dr. Sarah Arnette is a postdoctoral researcher in the Kolmann Lab whose work focuses on comparative biomechanics and functional morphology in fishes. She investigates how anatomical structures (e.g., suction discs, gizzards, and adhesive systems) contribute to animal performance and interaction with environments, with applications for bio-inspired design. Her recent publications include studies on suction performance in clingfish, highlighting the integration of behavior and morphology in biomechanical function.
...is a PhD student studying cranial integration, modularity, and the evolutionary biomechanics of mouth-brooding in anabantarian fishes (like Bettas!). Luke is also our resident paleontologist (in his spare time).
...will be starting their PhD in Fall 2026! Madison just defended her Master's at Wake Forest University on measuring the abundance of benthic communities in Belize using remote sensing.
...will be starting their PhD in Fall 2026! Madeline has multiple published papers on the plants and amphibians of the American southeast. She's considering the phylogeography & evolution of South American fishes for her dissertation!
Defended in Spring '26! Her research program focuses on the biodiversity of the Guiana Shield, including the description of new species, trophic ecology of fishes, and the biogeographic history of northern South America.
Current role:
Curator of Ichthyology, University of Guyana
Defended in Spring '26! Her research interests span the conservation, behavior, and morphology of burrowing crayfishes across the American Southeast.
Current role:
Curator of Invertebrates, Auburn University Museum
