Using both field- and lab-based geochemical methods, we are linking the molecular products of life with how organic signatures are preserved in the geologic record in deep time, touching on topics that range from the origin of life, evolution, astrobiology, climate change and more.

Cosmochemistry and Planetary Sciences

Applying various approaches such as remote sensing, geophysical modeling and cosmochemical analysis, we are investigating the origin of Solar System, the formation of planets and planetary surface processes. Our subjects of interest range from the Moon, Mercury, Mars, and Pluto to icy worlds to beyond our Solar System.

Environmental Sciences

Studying the geologic, climate, and aqueous environmental histories of Earth and other planets using methods that range from satellite remote sensing to nano-scale mineral surface reactions, and from the stratigraphic record to measuring active hydrology and climate change.

Geological Sciences

Our students and faculty are answering fundamental questions on tectonics, Earth history, soil science, sedimentology, petrology, climate science, and mineralogy; from Antartica to Mars we cover all aspects of geological sciences in the field, by experiments, and the lab.


Probing the interior of the Earth using a combination of geophysics, geochemistry, and geodynamics; our department studies the current state of our Earth as well as the Earth's interior in deep time with the most modern techniques in analytical geochemistry, deformation, seismology and numerical modeling.
