Biogeochemistry is a truly transdisciplinary field and bridges Life Sciences, Geosciences and Geochemistry. Biogeochemistry encompasses the study of fluxes of elements and energy in terrestrial (e.g., forests, riparian systems, desert soils and crusts) and aquatic (such as hot springs, lakes, rivers, oceans) ecosystems, as well as the roles, adaptations, interactions and the evolution of organisms in these environments. Biogeochemists work on processes that span across wide temporal (from geologic to present) and spatial (from micro to global) scales. In close collaboration with Biogeochemists in the School of Earth and Space Exploration and Department of Chemistry/Biochemistry (see list of faculty below), biogeochemists in the School of Life Sciences at ASU study microorganisms that modify rocks and minerals (Geomicrobiology); life in extreme environments, including those that bear resemblance with possible habitats on other planets (Astrobiology); the role of microorganisms in the flux of matter and energy in the ocean (Biological Oceanography), the balance of energy and multiple chemical elements in living systems (Ecological Stoichiometry), the role of biota in the flux of elements in terrestrial and aquatic ecosystems (Ecosystem Ecology), the role of hydrology and spatial heterogeneity in biogeochemical dynamics of desert landscapes (Ecohydrology), as well as the influence of urbanization on elemental cycles in the desert (Urban Ecology).

ACTIVITIES and COLLABORATIVE PROJECTS
Seminars
- Biogeochemistry Seminar/Reading Group (BIO 591, Fall Semester -- A seminar exploring recent topics in aquatic and terrestrial biogeochemistry
- Ecology and Evolutionary Biology Lunch (each semester) -- Graduate student organized luncheon which gives students the opportunity to present and discuss their research
- DirtWaterCell (each semester, credit available through CHM 501) -- A project-driven seminar; recent topics: biogeochemistry of dust, synthesis of gas hydrates, nanoparticles in the environment.
- Biogeochemistry Interest Group (BIG) -- A bi-weekly seminar held in most semesters and chaired by various faculty from SoLS and SESE as an informal forum for discussion of current research of BGC faculty and graduate students.
