We investigate the development and the structural and functional evolution of sensory systems. We primarily study the mechanosensory lateral line system of fishes, but we are currently investigating the contributions of all sensory systems to larval fish behavior. We use multiple morphological methods including histology, SEM, CT and µCT, vital fluorescent imaging, and fate mapping to gain a comprehensive understanding of lateral line morphology and development. Recent behavioral work has allowed us to add DPIV (for analysis of natural and artificial hydrodynamic stimuli), manipulation of the visual environment, video analysis of behavior, and fish training to our repertoire. Collaborative work is allowing correlation of morphological and behavioral development.  Over the years, we have studied the lateral line system in a variety of taxa (skates, zebrafish, greenlings, butterflyfishes, flounders, cichlids, and deep sea fishes). Each taxon has interesting or unique attributes that have allowed us to ask fundamental questions about patterns of lateral line evolution and development, as well as the functional morphology and role of the lateral line system in fish behavior. This work has been supported by several National Science Foundation grants (1997-Present), Rhode Island NSF EPSCoR, Marine Biological Laboratory (Woods Hole), and institutional funds.
