At SF State Since:
My research interests broadly span the co-evolution of life and the earth surface environment on geologic and recent timescales. As a sedimentary geologist and geobiologist, I use field, petrographic, and geochemical approaches to understand different scales of environmental change as recorded in the sedimentary rock record. Most of my work has been on the biogeochemistry of fluvial and lacustrine carbonate microbialites. My research offers a range of opportunities for students to study sedimentary rocks from a paleoenvironmental perspective as well as with a geobiological/astrobiological framework.
I teach courses in Earth Systems Science and Sedimentology/Stratigraphy.
