^*Sophie Warny is an Associate Professor and the AASP Chair in Palynology in the department of Geology and Geophysics and a curator at the Museum of Natural Science at Louisiana State University in Baton Rouge. She has a long history with AASP as she won the AASP Student Award in 1996, served as Director-At-Large on the AASP board from 2006 to 2007, was the AASP Newsletter Editor from 2006 till 2015, and is now the AASP Chair in Palynology. She received her Ph.D. from the Université Catholique de Louvain, in Belgium working with Dr. Jean-Pierre Suc on the Messinian Salinity Crisis. In 2011, she received a NSF CAREER award to conduct palynological research in Antarctica. Since being hired at LSU in 2008, she directed 18 graduate students' theses on various Cretaceous to Cenozoic sections. Her focus is the use of palynomorphs to reconstruct past climate or provide biostratigraphy. Her former students are mostly employed with the oil and gas industry (Hess, BP, Devon, Chevron, BHP Billiton Petroleum, and EOG), but also with the U.S. Department of Homeland Security, with environmental companies, with IODP, or as instructor.
^**David M. Jarzen is a Research Associate at the Cleveland Museum of Natural History, in Paleobotany and Paleoecology. He earned his B.S. degree in 1967 from Kent State University, and two years later received his M.A. degree in Botany from the same institution. In 1973 he was awarded the Ph.D. in Geology from the University of Toronto. His research interests in the nature of extant and fossil plant life have provided extensive field work around the world, incorporating a global view aiming to understand the evolution of plant life during Earth's history, with an emphasis on fossil floras recorded from the Paleogene, Neogene and Cretaceous. His work has been incorporated in several radio and television productions including CBC's “Nature of Things” with David Suzuki, the PBS NOVA Series, the NHK (Japan) Series “The Miracle Planet”, the National Film Board of Canada, the Discovery Channel and other North American cable networks. David was elected as Fellow National to the Explores Club, and in 2005 he was elected Fellow of the Ohio Academy of Science.
^***Shannon J. Haynes is a Research Specialist and Laboratory Manager at Princeton University in the lab of Dr. Xinning Zhang. She is also a PhD student at the University of Missouri. She earned her B.S. degree from West Virginia University in 2009. She worked with Dr. Brian Huber as an intern from 2009 to 2010 in the Paleobiology Department at the Smithsonian National Museum of Natural History (NMNH) where her research largely focused on the taxonomy of Turonian aged biserial planktonic foraminifera from Tanzanian drill cores. She earned her M.S. degree from the University of Missouri in 2012. The master's project expanded on work she began while interning at the NMNH and also looked at biomarker compositions from Tanzanian samples to better characterize the environment in which exceptionally well-preserved foraminifera were preserved in Tanzania. Shannon's PhD is done in collaboration with Dr. Kenneth MacLeod (advisor) and Dr. Ellen Martin (University of Florida). It focuses on the relationship between climate change and ocean circulation during the Late Cretaceous using neodymium isotopes from fossilized fish debris as a proxy to infer ocean circulation patterns. Currently she is finishing up her PhD work and is beginning a new research project that will be based on samples she collected on IODP Expedition 369 where she will work on regional neodymium isotope patterns to see how they relate to Mid-Late Cretaceous Ocean Anoxic Events.
^****Kenneth G. MacLeod is a professor of Geological Sciences at the University of Missouri. He teaches classes spanning the curriculum with a bias toward paleontology, paleoceanography, global change, and mass extinctions. Ken earned a PhD and masters in science in geology from the University of Washington and a bachelor of arts in biology and geology from Williams College. His graduate career began with studies of the systematics and distribution of the last inoceramid bivalves and has expanded since to focus on ancient greenhouse climates throughout the Phanerozoic, ocean structure and circulation in deep time, and mass extinction events with conclusions informed by integrating paleontological, geochemical, sedimentological and other data. He is the director of the University of Missouri stable isotope laboratory. He and his students have worked on projects from the Ordovician to the modern, but the Cretaceous remains an area of particular emphasis.
^*****Brian Huber is the Curator of Foraminifera at the Smithsonian's National Museum of Natural History's Department of Paleobiology. He received his B.Sc. in Geology from the University of Akron and M.Sc. and Ph.D. in Geology from The Ohio State University. His research focuses on changes in global climate from 115–35 million years ago and the evolutionary dynamics and extinction of Cretaceous and Paleogene planktonic foraminifera during that time interval. He was a shipboard paleontologist on several Ocean Drilling Program cruises and during Fall 2017 he was Co-Chief Scientist of IODP Expedition 369, which drilled offshore the southern and southwest Australian margin. He has also done fieldwork in Antarctica, southern South America, Spain, and coastal Tanzania. He has served on the Board of Directors and as President of the Cushman Foundation for Foraminiferal Research and as a member of several editorial boards and Ocean Drilling Program panels, he was on the Steering Committee and Board of Directors for the NSFCHRONOS initiative and he is a Voting Member of the and Vice-Chair of the International Commission on Stratigraphy.
