Julie B. Retrum

Julie B. Retrum is an Instructor in the Department of Geology and Geological Engineering at the University of Mississippi. She has held this position since 2017, following roles as a Research and Teaching Associate at Khalifa University (2014-2017) and Postdoctoral positions at the University of Minnesota (2010-2013).

Education includes:

• Ph.D. in Geology from University of Kansas (2010)
• M.S. in Geology from University of Kansas (2004)
• B.A. in Geology, Statistics, and Biology from University of Minnesota–Morris (2001-2002)

Research focuses on reconstructing past climates through geochemical and paleontological proxies, with emphasis on carbonate systems and isotopic analyses. Recent projects involve calibrating coral thermometry in extreme Persian Gulf environments and dating archaeological sites using coral samples.

Research trends from publications show consistent focus on:

• High-resolution paleoclimate reconstructions using speleothems and lacustrine sediments
• Development of novel geochronological methods
• Neoichnological approaches to interpret trace fossils
• Multiproxy analysis of Quaternary environments
