Geobiology & Astrobiology
Geobiology and Astrobiology are two vibrant and rapidly growing areas of interdisciplinary inquiry at ¶¶Òõ¶ÌÊÓƵ-Boulder with many of our faculty engaged in cutting edge research at the interface of the two fields.
Geobiology is the study of how physical, chemical and biological processes influence each other in natural systems.Ìý Geobiology research can focus on modern environments, as well as explore how the planet and life have co-evolved through major geologic and evolutionary events over the course of Earth’s history.Ìý
Astrobiology explores life in the context of the evolution of the universe; its emergence and the possibility for life to exist on other worlds in the solar system and beyond.
Geobiology
At ¶¶Òõ¶ÌÊÓƵ, we quantitatively explore how past environmental conditions, climatic transitions, and biogeochemical processes can be inferred from microbial isotopic fractionation, biomarker molecules and chemical sediments preserved in the geological record. ÌýWe explore microbial metabolic processes under conditions of slow growth and extreme energy or nutrient limitation. We also test evolutionary hypotheses by coupling isotopic approaches with microbial evolution experiments focused on geologically important classes of organisms. ÌýOur work moves between theory, experimental systems and a detailed analysis of the chemical, hydrological and biological states of the Earth through time.

Astrobiology
¶¶Òõ¶ÌÊÓƵ Boulder supports a wealth of Astrobiology research and educational activities on our campus, which are often coordinated through the . In our Department, Astrobiology research and teaching is primarily focused on life and hydrological conditions in extreme environments, biosignature identification, the study of the primordial Earth and Mars.ÌýWe are also connected to current and the NASA Astrobiology Institute “ node.ÌýFor more details on the astrobiological research taking place in our department, please visit the profiles of our faculty with primary research programs in Astrobiology:
OtherÌýfaculty interested in Geobiology & Astrobiology
In addition to those listed above, several other faculty in our department with primary research programs in other areas have a researchÌýinterest in Geobiology and AstrobiologyÌýand frequently collobarate on research projects and serve as thesis committee members for ourÌýgraduate students.
