A common thread of my research has been the use of high-dimensional stable isotope systems to read geological, biological, and environmental records, as well as reaction pathways:

Middle atmosphere; ancient atmosphere on Earth; Earth history; Mars; applications of isotope effects in chem/bio-engineering.

Modern- and paleo-atmosphere chemistry  

Interfacial (e.g. mineral growth and dissolution; evaporation) processes

Chemical including enzymatic reaction kinetics

CHNOPS and water cycles in deep Earth history
