Morning Plenary session dedicated to honoring John and Vicki Pearse for their many contributions to and support of echinoderm research and researchers!

Read more about John and Vicki by clicking on the Dedication tab above.

Plenary speakers for this session are:

Isidro 'Sid' Bosch is Professor of Biology at S.U.N.Y. College at Geneseo in Geneseo, New York. He received his Bachelor of Arts degree in Aquatic Biology from the University of California at Santa Barbara and his doctoral degree in Biology from the University of California at Santa Cruz under the direction of John Pearse. After completion of his doctoral degree, Sid held several prominent postdoctoral positions including ones at the Harbor Branch Institution, Inc. and the University of California San Francisco. He has been a member of the faculty at S.U.N.Y. College at Geneseo since 1992. Sid has also worked closely with Vicki Pearse, studying larval feeding in the Antarctic and California. He has garnered excellence in both teaching and research awards and has published a large body of work on both marine and freshwater organisms. He is currently studying the nature of a symbiotic relationship between North Atlantic sea star larvae and the bacteria found beneath the cuticle along the sea star gut region.

James B. McClintock is the Endowed University Professor of Polar and Marine Biology at the University of Alabama at Birmingham. Jim worked with John Pearse as both an undergraduate student and as a National Science Foundation Postdoctoral Fellow. He received his Bachelor of Science degree from the University of California at Santa Cruz and his doctoral degree from the University of South Florida. He became a Full Professor at UAB in 1997 and has served as Dean of the School of Natural Sciences and Mathematics (1999-2003) and as Interim Dean of the Graduate School (2003-2005). Dr. McClintock’s research has been funded continuously over the past 25 years by the National Science Foundation and focuses on aspects of marine invertebrate nutrition, reproduction, and primarily, Antarctic marine chemical ecology. He has published over 250 scientific publications, edited and written books, been invited to make numerous scientific and popular science presentations, and his research has been featured in a variety of public media outlets such as the NPR Diane Rehm Show, NPR’s “On Point” with Tom Ashbrook, National Geographic Magazine, and the Washington Post, among others. He has been the recipient of numerous awards and distinctions including recognition for excellence in teaching and research. In 1998 the United States Board on Geographic Names designated the geographic feature “McClintock Point” in honor of his contributions to Antarctic science.

Ben Miner is an Associate Professor in the Biology Department of Western Washington University. He earned his Bachelor of Arts from the University of California at Santa Cruz and was advised in his research by John Pearse and Grant Pogson. Ben received his doctorate from the University of Florida working under the late Larry McEdward and spent several summers at the University of Washington’s Friday Harbor Laboratories. Post-doctoral studies were at the University of California at Davis’ Bodega Marine Laboratory and Center for Population Biology, working with Steven Morgan and Rick Grosberg. Ben’s recent research has focused on the underlying causes and ecological ramifications of sea star wasting disease in the Pacific Ocean. Other research efforts have focused on phenotypic plasticity and inducible offenses in echinoderm larvae and marine gastropods.

Speakers: David L. Pawson and Doris J. Pawson

Dave Pawson is an Emeritus Senior Research Scientist in the Department of Invertebrate Zoology at the Smithsonian Institution’s National Musuem of Natural History in Washington, D.C, where he’s worked since 1964. Dave received his B.Sc., M.Sc., and Ph.D. degrees from Victoria University in New Zealand, and came to the U.S. when his doctoral advisor, H.B. Fell, became a professor at Harvard University. Dave’s research efforts have focused primarily on the taxonomy, ecology, and reproductive biology of echinoderms, particularly sea cucumbers and sea urchins. He’s also long been fascinated by the biology of organisms inhabiting isolated island groups. His recent work, published with his long-time collaborator and wife, Doris, documents echinoids and holothuroids found via manned submersible and remotely operated vehicles in deep-sea coral and cold seep habitats in the northern central Gulf of Mexico continental slope, off Mississippi and Louisiana.
