My research aims to understand the patterns and processes that underlie disturbance and ecosystem recovery, particularly how shifting fire regimes are reconfiguring tropical forests, encouraging non-native grass invasion, and affecting the global climate. My current and future research addresses the following major unsolved questions: 1) What is fire’s role in the Earth system? More specifically, how does fire contribute to global trends of climate warming and how does climate warming promote fire? 2) How are fire regimes altered by invasive species? Particularly, how is an invasive grass-fire cycle established and perpetuated? 3) How is the recent, unprecedented increase in human-initiated fires altering tropical-forest dynamics, and how has this increase in fire frequency changed carbon cycles and the recovery trajectory?

GEOG 1001 - Environmental Systems: Climate and Vegetation
Lect. and lab. Introduces the atmospheric environment of the Earth: elements and controls of climate and their implications for hydrology, vegetation, and soils. Emphasizes distribution of physical features across the Earth's surface and interactions between humans and their environment, especially those leading to global change on the decade to century time scale.
