Untitled-1Agriculture is the dominant driver of terrestrial ecological change, and its impacts will continue to grow in the next few decades as our demands for food, fuel, and fiber increase. I am primarily interested in understanding how this continued agricultural development can be achieved for substantially lower environmental, and thus social, cost.  My work investigates three inter-related aspects of this problem:

I study these issues across multiple scales of time and space, ranging from continental perspectives down to the level of individual rare species. I focus primarily on sub-Saharan Africa, where agricultural development is likely to be most rapid in the coming decades.
