Kathy Hibbard has been an AGU member since 1994. She began in the Atmospheric Sciences section and transitioned into Biogeosciences in 2000. Her current position is with the National Center for Atmospheric Research in Boulder, Colorado, as Project Scientist II and Executive Officer for the International Geosphere-Biosphere Programme's (IGBP) Earth system project, the Analysis, Integration and Modeling of the Earth system (AIMES). Her major area of scientific interest is in understanding the consequences of disturbance (natural and anthropogenically forced) to terrestrial biogeochemical cycles through field observations and modeling. Her primary focus in the new AIMES project is to understand and integrate human-environmental processes (e.g., land use, emissions) in Earth system modeling. She received a B.S. and M.S. from Colorado State University in Biology and Range Science, 1982 and 1987, respectively; and a Ph.D. from Texas A&M University, Range Ecology and Management, in 1995. She has authored/coauthored 25 refereed publications and two book chapters, and has worked in international program development for the IGBP's Global Carbon Project and IGBP/GAIM Task Force. She has been a member of the Ecological Society of America since 1991 and served AGU Biogeosciences from 2001 to 2004 as Fall Meeting Program Committee Representative.
