It’s often assumed that all soil organic carbon ultimately derives from recent vegetation, but researchers argue that carbon inherited from parent rocks can be important and deserves more focus.

I am a chemical sedimentologist: I study how and why chemical sediments form and lithify, with the goal of better understanding how chemical sedimentary rocks ... of fossil life forms and depositional ...

Microfluidics experiments and simulations show that magnetotactic bacteria are adapted to the geomagnetic field strength for optimal navigation in sediment environments.

We are particularly interested in resolving the architecture and depositional history of sedimentary strata deposited in shallow-marine environments, and we employ a wide range of qualitative (e.g., ...

My work on the neoichnology and sedimentology of shallow marine depositional environments includes characterizing ... 2012 James Lee Wilson Award Bestowed by the SEPM (Society for Sedimentary Geology) ...
