Within the Department, geosciences research focuses on the physical, chemical, and biological processes that converge near Earth’s surface. This varied work connects the solid Earth with the hydrosphere, cryosphere, atmosphere and biosphere. Our areas of active research include: geomorphology, from mountains and coasts to seascapes and planetary surfaces; the dynamics and deposits of glaciers, rivers, coastal and marine environments; regional and global impacts of climate change; Earth history from formation to present; low-temperature and isotope geochemistry; and organic geochemistry and biogeochemistry. Our teaching and mentorship prepare students and postdoctoral associates for careers in fundamental research, government, education, environmental consulting and law, community planning, resource management, and other disciplines that rely on quantitative and rigorous understanding of Earth’s environments.
