John H. Costello is a Professor in the Department of Biology at Providence College's School of Arts and Sciences. His research examines marine organism-fluid interactions with emphasis on gelatinous zooplankton feeding mechanics and ecological impacts.
Dr. Costello's primary research areas include Marine Biology, Ctenophore Research, Hydrodynamics, and Trophic Ecology. His work investigates how oceanic lobate ctenophores generate feeding currents through laminar flow mechanics, analyzing morphological adaptations and behavioral strategies across multiple species. Current research focuses on quantifying trophic impacts in epipelagic ecosystems by comparing oceanic and coastal ctenophore species.
His 2022 publication in Limnology and Oceanography demonstrates that despite morphological diversity, five lobate ctenophore species employ similar laminar feeding current mechanisms. The research reveals how behavioral differences in swimming posture significantly affect prey encounter rates, suggesting oceanic ctenophores may exert greater trophic pressure than previously estimated.
Dr. Costello collaborates extensively with marine research institutions including the University of South Florida, Oregon Institute of Marine Biology, and Roger Williams University, contributing to interdisciplinary studies of planktonic ecosystem dynamics.
