Research Areas


Atmospheric Sciences

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

Testing the water

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.

Mountain ranges

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.

Spacecraft mission

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.

CALTECH — David Zierler, Director of the Caltech Heritage Project at CalTech, caught up with Prof. Doug Schmitt, CalTech alumnus and current Purdue EAPS Associate Head, Professor, and Stephen and Karen Brand Endowed Chair of Unconventional Energy, to discuss his career in rock physics.

Purdue Team of Scientists Return from Trip to Antarctica


STAR CITY NEWS — Hannah Grace, of Star City News, sat down with Dr. Marissa Tremblay, of Purdue Earth, Atmospheric, and Planetary Sciences, to discuss her recent trip to Antarctica.

Lifting the Veil


SCIENCE — Alien planets are shrouded in hazes that hide clues to their makeup. Lab experiments could help clear the view. Dr. Alexandria Johnson, of Purdue EAPS, is cited in this article by Some researchers, like Johnson, are focused on exoplanet clouds, who grows and studies clouds in a chamber. She wonders how clouds and hazes might interact on an exoplanet—whether, for example, haze particles might promote cloud formation by providing “nucleation sites” for gases to condense.

Geochemist leads an all-woman team onto the ice in Antarctica


PURDUE NEWS — Dr. Marissa Tremblay, assistant professor of Purdue EAPS, led her team of science experts – all of whom happen to be women – into the wilds of Antarctica to research the climate history of the continent – and the planet.
