Michael Boyle is Biologist and Principal Investigator of the Life Histories Program at the Smithsonian Marine Station. Dr. Boyle is an early-career scientist with doctoral and post-doctoral research experience on comparative development of embryonic and larval stages of marine annelids. He is an expert on the imaging of larval invertebrates with confocal laser scanning microscopy. His laboratory focuses on describing molecular, genetic, and developmental diversity of marine invertebrate life cycles. Craig Young is Professor of Biology at the University of Oregon, and past Director of the Oregon Institute of Marine Biology. Dr. Young has devoted his professional career to investigating the reproduction and early life-history stages of marine benthic invertebrates at all depths of the sea, and his lab pioneered the culture of larvae from deep-sea environments worldwide. Dr. Young, the founding editor of Atlas of Marine Invertebrate Larvae, returns to the second edition as co-editor. Mary A. Sewell is a Professor of Biological Sciences at the University of Auckland, New Zealand. She is an authority on the larval form, physiology, and ecology of echinoderms, with research on species from the tropics to the Antarctic and from the intertidal to abyssal depths. Dr. Sewell returns to the second edition of Atlas of Marine Invertebrate Larvae as associate editor.
