We study extreme weather, climate change, and their impacts on both ecosystems and modern society.
Atmospheric Sciences
Environmental Geoscience
We use biology, chemistry, geology, and physics to understand how the Earth System supports such a diversity of life and how human behavior is impacting this system.
Geodata Science Initiative
Data science is the fourth and the newest paradigm of science. In Geodata Science Initiative, we conduct transdisciplinary research, merging or articulating EAPS subject matters with technical areas in data science: statistical and machine learning methods and models, algorithms for the models and methods, and computational environments for data analysis.
Geology and Geophysics
We study the processes that shape our planet, from the building of mountains and oil-bearing sedimentary basins, to the flow of warm rocks and cold glaciers, to the triggering of earthquakes.
Planetary Science
We study the evolution of the solar system and how planets evolve over time due to impacts, tectonics, and atmospheric processes, with an eye to the potential for past and future habitability.

Satellites encased in wood are in the works
01-27-2026
The Economist — Swapping metal for wood, though, is not without hazard, observes Daniel Cziczo of Purdue University, who was one of the authors of the stratospheric-particle study. What might emerge from a reaction between the resulting soot and vaporized electronics remains unknown. The article requires a login.
