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

Moon's largest scar may put its deepest secrets within reach of Artemis astronauts
05-26-2026
Billions of years ago, something enormous slammed into the far side of the Moon and left behind a scar so large it stretches more than 1,200 miles across the lunar surface. That ancient feature, known as the South Pole-Aitken basin, is the oldest and largest known impact basin on the Moon. It also may hold some of the best clues to what lies deep inside Earth's nearest neighbor.

Rubies and opals on Mars? The real treasure in the planet’s gemstones may not be what you think
05-12-2026
Scientific American — NASA’s Mars rovers have found traces of minerals akin to those that make up precious gems on Earth. But their appearance and abundance on Mars is likely very different, experts say. EAPS's Candace Bedford was a co-author of the study.
