Research Areas

Tornado

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.

Purdue announces new head of the Department of Earth Atmospheric, and Planetary Sciences

12-06-2024

After a competitive search, Purdue University announced Andrea Donnellan will take on the role of head of the Department of Earth, Atmospheric, and Planetary Sciences (EAPS) effective January 1, 2025. Donnellan was manager of the Instrumental Systems Section at NASA’s Jet Propulsion Laboratory (JPL) where she was also a senior research scientist before her taking this role at Purdue University’s College of Science.

Purdue scientist expecting new world to reveal itself to Mars rover

12-04-2024

NASA’s Mars 2020 rover mission and Purdue planetary scientist Briony Horgan are approaching a new phase in the search for details about the red planet’s history and potential for previously hosting life. The mission’s Perseverance rover is only weeks away from emerging from the 28-mile-wide Jezero Crater to explore new terrain. It’s a point in the mission Horgan set her sights on following the rover’s landing in the crater four years ago.

Purdue researchers use traffic jam theory to explain atmospheric blocking

11-18-2024

Atmospheric blocking is an extreme weather event associated with potentially significant socio-economic losses. It can be devastating to a community when it happens and researchers would like to understand the phenomena better. A team of researchers from Purdue University applied a traffic jam theory to explain atmospheric blocking. The team was led by Lei Wang, assistant professor with the Department of Earth, Atmospheric, and Planetary Sciences at Purdue University. They published their results in Geophysical Research Letters.

Harbor named Purdue Global interim chancellor

11-13-2024

Chris Ruhl, Purdue Global interim CEO and Purdue University chief financial officer, announced today (Nov. 13) that Jon Harbor will serve as Purdue Global’s interim chancellor beginning Jan. 1, assuming the role of Frank Dooley, who announced Nov. 6 that he will step down at the end of 2024. Harbor is an emeritus professor of Purdue EAPS.

Meteorite contains evidence of liquid water on Mars 742 million years ago

11-06-2024

Eleven million years ago, an asteroid struck Mars and sent pieces of the red planet hurling through space. One of these chunks of Mars eventually crashed into the Earth somewhere near Purdue and is one of the few meteorites that can be traced directly to Mars. This meteorite was rediscovered in a drawer at Purdue University in 1931 and therefore named the Lafayette meteorite. During early investigations of the Lafayette meteorite, scientists discovered that it had interacted with liquid water while on Mars. Scientists have long wondered when the interaction with liquid water took place. An international collaboration of scientists including two from Purdue University’s College of Science have recently determined the age of the minerals in Lafayette that formed when there was liquid water. The team has published their findings in Geochemical Perspective Letters.
