My major research foci are a) using the TEM model to determine the effects of tropospheric ozone on vegetation production and carbon storage, b) using TEM coupled to the MIT Integrated Global Systems Model to determine the economic consequences of policy decisions regarding air quality, c) developing more realistic carbon, water, and nitrogen linkages to capture the effects of carbon and nitrogen feedbacks on the hydrological cycle, d) exploring land use and land cover change implications for carbon dynamics, especially with respect to future crop growth for biofuels, and e) using global and regional climate models to understand climate change in the past and to determine the impacts of future climate change on ecosystems and the hydrological cycle. I have more recently been awarded funding from NSF’s Macrosystems Biology program to explore the effects of climate extremes (floods, droughts) on ecosystem functions and services, and from NSF’s Interdisciplinary Behavioral and Social Science (IBSS) program to study the effect of climate disasters on food supplies within a range of human societies.
