Research Interests:

Energy exchange at the Earth's surface - The exchange of energy between the atmosphere and the ground controls the temperature in the upper few meters of the earth. Understanding the partitioning of energy at this boundary is of fundamental importance if ground temperatures are to be used as an indicator of past climatic variations. Snow cover, vegetation, radiant heating, and micro-scale atmospheric dynamics play roles in mediating this exchange. Additionally, the land surface is the most poorly parameterized component of global climate models. Better understanding of the ineraction between the solid Earth and the atmosphere will inevitably improve the skill of our climate model predictions.

Moderate complexity climate modeling and global climate feedbacks - The feedbacks that regulate the global climate system are complex; fully understanding the influence that changes in one part of a regional climate system have on the global system is necessary if we are to pursue policies aimed at mitigating unwanted climatic variations. Current methods of investigation rely on experimental Earth science - performing large-scale simulations of the global climate system on computers. However, the level of detail available in "state-of-the-art" GCMs is often a hinderance to our gaining a real insight into the internal relationships in the climate system. More concentrated effort on moderate complexity models specifically designed to perform relational experiments could prove extremely fruitful. Additionally, as our ability to observe the climates of other planets improves, comparative climatology may play an important role in increasing our understanding.

Regional-scale climate modeling and forecasting - Climatic variations have shaped the history of cultures throughout recorded history and pre-history. We are nearing a time in which we will have the capacity to accurately predict regional scale climate changes on a time frame of economic interest. Such forecasts are of interest since policy decisions are most often driven by regional scale interests. As an example, the sensitivity of our economic system to climatic variations, while debated in academic circles, is actively speculated on by the economy as a whole (via weather risk management). Improving the skill of regional climate forecasts will involve both better model parameterization (ie. better observational input) and a more detailed understanding of the scale relationships within the climate system.

Economic, social, and political consequences of global change - Humanity's influence as an ecological, climatic, and geological agent of global change is rapidly growing. There are increasingly large consequences to our decisions about population growth, energy and resource consumption, and our philosophical view of the natural world. Making rational decisions about our economy, social structure, and environment requires that we have a good grasp of the many ways in which they interact with one another. Unfortunately, economic and environmental views are often seen as incompatible or competing. Many interesting problems are found at the interface between our economic and environmental well being such as the ability of markets to deal with intrinsically valued resources and our capacity to forecast economic consequences of environmental alteration.

Thermal aspects of geological problems - Many problems in Earth science are either driven by or involve the transfer of thermal energy. Heat is what makes our planet a lively, interesting place. I am interested in the manner in which traditional thermal geophysical studies can inform problems in tectonics, geomorphology, and structural studies of the solid Earth and other planets. If temperature is in the equation, I am interested.
