Wilfred M. Post
Wilfred M. (Mac) Post is a science team leader of the Ecosystem Simulation Science group in the Ecosystem Science Group of the Environmental Sciences Division at ORNL. This team focuses on the role of terrestrial ecosystems in the global carbon cycle and climate change. This is accomplished by developing process based simulation models in collaboration with field and laboratory scientists and implementing them in high-performance computer models of the global climate system.
Post’s particular emphasis is in the area of global terrestrial ecosystem carbon cycling and relationships of ecosystem dynamics to environmental, edaphic, and biological conditions. He is a recognized expert on soil carbon dynamics, nutrient relationships between soil and vegetation, and the impact of species composition on ecosystem processes. He has developed new approaches to representing the impact of climate change in terrestrial biogeochemistry models and also developed global data sets for the evaluation of global terrestrial biogeochemistry models. Post’s current work centers on developing data-assimilation methods to confront terrestrial ecosystem models with data from a variety of sources to estimate model parameters and initial conditions and to improve ecosystem models. He holds an adjunct professor position at the University of Tennessee at Knoxville and is author or co-author of over 90 scientific or technical publications.
Post has served as a member of the National Aeronautics and Space Administration Distributed Active Archive Center for Biogeochemistry User Working Group, North American Carbon Program, Carbon Cycle Science Steering Group, contributing author of the U.S. Carbon Cycle Plan, and associate editor for the American Naturalist.
