James Ogg serves as an Adjunct Professor in the Department of Earth, Atmospheric, and Planetary Sciences (EAPS) at Purdue University's West Lafayette campus. He maintains active research engagement through the Vertically Integrated Projects (VIP) program, which integrates undergraduate students into long-term, large-scale geoscience research initiatives.
His research spans stratigraphy, paleoclimatology, geochronology, and paleontology, with emphasis on reconstructing Earth's history through sedimentary records and orbital climate forcing. Notable contributions include refining the geomagnetic polarity timescale, analyzing mass extinction events, and investigating paleoclimate dynamics across critical intervals like the Late Paleozoic Ice Age and Eocene-Oligocene transition. His work frequently employs cyclostratigraphy and database integration to resolve temporal frameworks.
Analysis of his recent publications reveals a dominant focus on deep-time database development, particularly through the Deep-Time Digital Earth (DDE) program. His research demonstrates strong international collaboration, especially in Asian geological contexts, addressing supercontinent dynamics, paleoceanographic changes, and the interplay between tectonics and climate systems. Key recurring themes include carbon cycle perturbations, monsoon evolution, and stratigraphic correlation across paleogeographic reconstructions.
Within the VIP program, Dr. Ogg mentors students in projects bridging theoretical geoscience with practical database applications, fostering hands-on experience in Earth system analysis and digital reconstruction of geological history.
