Research Areas
Atmospheric Sciences
We study extreme weather, climate change, and their impacts on both ecosystems and modern society.
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.

Is Indiana seeing more tornadoes than in the past? The answer is complicated and nuanced
04-04-2025
As Hoosiers clean up from severe storms Wednesday that battered central Indiana, scientists studying the climate say the state is likely to see an increase in the number of tornado outbreaks in the future. That prediction is based on research by the Midwestern Regional Climate Center based at Purdue University and the National Weather Service.
