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.

Which planets are the youngest and oldest in our solar system?

Live Science — About 4.6 billion years ago, a celestial cloud collapsed, paving the way for our solar system to form. Then, a nebula with strong gravitational pull took shape, kick-starting the birth of the sun. But after that, the details leave more room for debate about which planets formed first. Purdue EAPS's Cauê Borlina was quoted in the article.
Daniel Cziczo elected 2025 AGU fellow
09-25-2025
Daniel Cziczo, Purdue University Department of Earth, Atmospheric, and Planetary Sciences (EAPS) professor, was elected as an AGU Fellow, joining a distinguished group of 52 individuals in the 2025 Class of Fellows. AGU, the world's largest Earth and space science association, bestows this honor annually to a select number of individuals who have made exceptional contributions. Since the program’s inception in 1962, less than 0.1% of AGU members have been selected as Fellows each year.
Engineering meets science: Purdue collaboration aims to personalize nutrition through digital health

Metabolic diseases such as diabetes affect millions worldwide, profoundly impacting health, quality of life, and healthcare costs. Yet most dietary guidance relies on generalized recommendations and intermittent blood tests, which can miss real-time changes in metabolism that are critical for personalized care. A new project led by Purdue University faculty aims to change that.
Purdue University professor helping discover ancient life on Mars
09-18-2025
WTHR — The Perseverance rover landed in the Jezero Crater in February 2021 to explore the ancient Neretva Vallis River Valley. Last summer, it drilled the Sapphire Canyon sample from a rock called Cheyava Falls. Scientists believe the leopard spots found on it may have been made by ancient life, NASA said. The SuperCam is just one of seven instruments on Perseverance. EAPS's Roger Wiens can operate it from online software right in his Purdue office.

A new study led by Purdue University researchers has uncovered why some hurricanes grow significantly larger than others and why this growth occurs rapidly under certain ocean conditions. The research shows, for the first time, that hurricanes grow in size much faster when traveling over locally warm waters where the ocean surface is significantly warmer than the rest of the tropical oceans.
