Biography
I am an assistant professor at the University of Cincinnati in the Department of Geology specializing in Precambrian Paleobiology, Biogeochemistry, and Astrobiology. I am interested in learning everything I can about the origin and evolution of the earliest life on Earth, namely bacteria, cyanobacteria, archaea, and their distant relatives (see my Research page). I go about studying fossils of these groups via standard microscopy, as well as confocal laser scanning microscopy and Raman spectroscopy
Research Interest
Precambrian Paleobiology and Biogeochemistry: Early evolution of life on Earth; Archean fossil record of South Africa and Australia; Astrobiology; geologic record of microbial metabolic evolution; Mesoproterozoic terrestrial microbial ecosystems; kerogen geochemistry; in situ morphological and geochemical analyses of Precambrian microfossils.
