Bio:

Sedimentology, geobiology, carbonate geochemistry, diagenesis. My research uses the tools of sedimentology to understand what evidence of microbial communities can enter the rock record, how we recognize these deposits, and what sorts of observations in modern microbial ecosystems can give us useful search patterns to bring back to the rock record. The majority of Earth history is microbial, so these sediments serve as a window to key evolutionary transitions and changes in habitats through time. Current research projects integrate field studies and laboratory analysis to explore microbial habitats of modern ice-covered Antarctic lakes and assess Neoproterozoic (1000–541 million years ago) environments surrounding the expansion of complex life.
