Understanding the origins of life on Earth and beyond.
Our Research
We study life’s chemical and physical evolution, from its pre-solar beginnings through planetary formation to the emergence of life on Earth. We search for signs of life on other planets and we document the nature of microbial life at extreme conditions as well as the characterization of organic matter in fossils here on Earth. Our team was one of the foundational members of the NASA Astrobiology Institute (NAI).

Tools of the Trade
We utilize a wide range of spectroscopic instrumentation for the interrogation of the molecular structure, chemical, and isotopic composition of natural organic materials of biological and non-biological origin, including Raman, FTIR, GC-mass spectroscopy, solid-state NMR, electron microprobe, SIMS, EPMA, and SEM. We also operate chemical and experimental labs for culturing, synthesis, and characterization of organic materials.
