Short Biography

Research: Rob is a Research Hydrologist / Aquatic Biogeochemist with the Central Branch of the National Research Program, Water Resources Mission, Boulder, Colorado. His research focuses on the role of inland waters in the global carbon cycle and on hydrologic, climatic, and disturbance controls on the biogeochemical cycling and transport of aquatic carbon. His research emcompases a broad range of field, laboratory and modeling studies, including the transport of inorganic and organic carbon by surface and subsurface waters; the production, consumption and atmospheric exchange of carbon dioxide and methane by inland waters and soils; and extrapolation of aquatic carbon biogeochemical cycling processes and rates of carbon exchange from site to regional, continental, and global scales. Rob is the lead aquatic scientist for USGS LandCarbon studies of Ecosystem Carbon Sequestration and Greenhouse Gas Exchange. He is also the Principal Investigator of the NASA Arctic-Boreal Vulnerability Experiment (ABoVE)  project "Aquatic Vulnerabilites of Inland Waters and the Aquatic Carbon Cycle to Changing Permafrost and Climate Across Boreal North America".

Education: PhD: University of Wisconsin - Madison; Oceanography and Limnology; MSc: Univeristy of Illinois - Urbana; Biology / Aquatic Ecology; BSc: Western Illinois Univeristy - Macomb; Zoology / Botany

Other Activities: 

Member of the Carbon Cycle Science Steering Group (CCSSG) of the U.S. Global Change Research Program, U.S. Carbon Cycle Science Program

Associate Editor: American Geophysical Union, Journal of Geophysical Research - Biogeosciences
