Dr. Kristen St. John is a Professor of Geology at James Madison University. She earned her B.S. in Geology at Furman University (1992), and her M.S. (1995) and a Ph.D. (1998) in Geoscience from The Ohio State University. Her research focuses on geoscience education and the marine sediment record of past climate conditions. She was the Editor-in-Chief (2012-2017) of the Journal of Geoscience Education. An active researcher in the International Ocean Discovery Program (IODP), she has sailed as a marine sedimentologist on several ocean expeditions. Her teaching responsibilities include a large general education course on Earth systems and climate change, Earth science for pre-service teachers, and courses for majors on geowriting and communication, and on paleoclimatology/paleoceanography. She received the JMU General Education Distinguished Teacher Award in 2013 and the JMU College of Science and Math Outstanding Teaching Award in 2014. She was recognized as Geological Society of America (GSA) Fellow in 2016.Dr. Lawrence Krissek is an Emeritus Professor of Geology at The Ohio State University, and earned his PhD at Oregon State University. He is a clastic sedimentologist, with primary interests in the evolution of climates and ocean environments at high latitudes during the past 65 million years. In particular, he and his students have focused on the Late Cenozoic history of ice-rafting in the Northern Hemisphere, and on the mineralogical and geochemical records of Cenozoic sediment sources and weathering patterns in the Ross Sea sector of Antarctica. He also maintains an active interest in earth science education, including: 1) developing activities for classroom use, 2) identifying common misconceptions about earth science topics, and effective strategies for conceptual change, and 3) conducting effective professional development for pre-service and in-service educators. His work has been supported by NSF (Polar Programs, Ocean Drilling, and Geoscience Education) and the Ohio Board of Regents. He has won several awards for teaching, and publishes in a variety of peer-reviewed journals.
