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.

Purdue’s Mars team digs up 'Hogwallow' rocks that could hold life’s oldest secrets
04-17-2025
Scientists from Purdue University have identified a region on Mars that may provide clues about the red planet's potential to have once supported life. Their research focuses on "Hogwallow Flats," a distinct area within the Jezero Crater explored by NASA's Perseverance rover. The study, led by Purdue Postdoctoral Researcher Adrian Broz, has been published in the Journal of Geophysical Research.
Purdue professor reflects on NASA Challenger disaster, shares role in space shuttle's creation

Video: NASA asteroid samples give a snapshot of the past
04-10-2025
Michelle Thompson, associate professor of earth, atmospheric and planetary sciences, describes OSIRIS-REx — NASA’s first mission to bring asteroid samples to Earth — and what scientists have learned from the samples since they arrived in 2023. Unlike the constantly shifting conditions on Earth, objects in space like asteroids have not been significantly altered since they were formed 4.5 billion years ago.
Are we alone in the universe? These Mars rocks could finally give us an answer.
