Daniel Speiser

Dr. Daniel Speiser is an Associate Professor in the Department of Biological Sciences at the McCausland College of Arts and Sciences, University of South Carolina. His research focuses on the evolutionary physiology of marine invertebrates, particularly their visual systems and sensory adaptations.

• Visual Ecology: Studies spatial resolutions, spectral responses, and temporal dynamics of vision in molluscs and crustaceans for predator/prey detection and navigation.
• Distributed Visual Systems: Investigates neurobiology of multi-eyed molluscs like scallops and chitons with decentralized processing.
• Complex Trait Co-evolution: Analyzes functional relationships between sensory and locomotory systems in marine invertebrates.
• Biology of Color: Examines pigment-nanostructure interactions in color production, focusing on butterfly Speyeria.
• Natural Armor Systems: Explores trade-offs between protection and sensory function in structures like snapping shrimp orbital hoods and chiton shells.
