I am interested in biogeochemistry and geobiology with the following themes:
- lipid chemistry of geologically significant microbes and microbially dominated ecosystems
- organic and isotopic indicators of climate change, biotic evolution and mass extinction
- age- and environment-diagnostic biomarkers in sediments and petroleum
Archean, Proterozoic and extraterrestrial biogeochemical fossils
I've been lucky enough to work with some great people, and have a hand in all the research going on in the MIT Geobiology lab.
Professional Preparation, Appointments and Activities
At the Summons lab at MIT we study organic matter from microbes, environmental samples, and rocks. Ancient rocks and oils contain a rich abundance of hidden information within, including molecular and isotopic signatures of the organisms that existed at the time the organic matter was formed. The goal of our research is to extract and interpret these signals, in order to reconstruct ancient environments and understand how life evolved within them.
