Research Interests and Activities

Reinhard’s research involves combining techniques and theory from geology, oceanography, biogeochemistry, and planetary science to understand how Earth surface environments have changed through time, how this evolution has been coupled with the evolution of the biosphere, and how this knowledge can be generalized for application to other planetary environments. His focus includes the chemical evolution of Earth's oceans and atmosphere, development and application of isotopic and trace element paleoproxies, biogeochemical dynamics in modern oxygen-deficient aqueous environments, and the emergence and long-term stability of planetary 'biosignatures'. These biosignatures provide strong evidence for the presence of life at a planet’s surface. Reinhard recently received a three-year grant from NASA’s Exobiology Program to develop a model of Earth’s early atmosphere and ocean, about 4 billion years ago, when the planet was devoid of oxygen. “We think this research will provide significant steps forward in our predictive understanding of the links between microbial metabolism and atmospheric chemistry, and will refine our understanding of the early evolution of Earth’s biosphere,” Reinhard says. “Our ultimate aim is to develop robust atmospheric biosignatures for future analysis of extrasolar worlds, while providing computational tools for understanding the deep past and forecasting the long-term future of Earth’s biosphere.”

Prior to joining the UC Riverside faculty, Reinhard was an O.K. Earl Postdoctoral Fellow a the California Institute of Technology. He is currently the Associate Editor ofPaleoceanography and Paleoclimatology and a member of the Steering Council for NASA’s Nexus for Exoplanet System Science (NExSS).
