معرفی
Donald E. Penman is an Assistant Professor in the Department of Geosciences at Utah State University. His research focuses on the interactions between climate, oceans, and biogeochemical cycles through geochemical analysis of sedimentary records and numerical modeling. Penman uses advanced techniques like isotopic and trace metal analysis of sediments/microfossils to study Earth's past climates, particularly periods analogous to current climate change.
- Research specialties: Paleoceanography, Sedimentology, Geochemistry
- Key projects: Silicate weathering feedbacks, Eocene climatic optimum studies, Cretaceous-Paleogene extinction mechanisms
Recent work includes a funded USU Seed Grant studying siliceous microfossils and silicate weathering. He advises graduate students (Chels Howard, Ollie Laub) and actively recruits motivated researchers. Penman's research spans from Snowball Earth events to hyperthermal episodes, emphasizing coupled carbon-silica cycle dynamics. He frequently presents at international conferences and collaborates globally on IODP projects.
Recent publications explore ocean acidification during the MECO, hydrologic changes during PETM, and the role of silicate weathering in climate regulation. He combines fieldwork, lab analysis, and computational modeling to advance understanding of Earth's climatic history.
