Christopher Comer, Dean
Associate Professor of Hydrology and Hydrologic Modeling:
My research takes an interdispciplinary view of hydrology that considers the hydrologic cycle as the background process that sustains and connects ecological and landscape processes.Under this perspective, the study of how water flows in the landscape is both a final objective and a means to achieve an integrated understanding of our environment.
Our mission can be summarized in three broad topics:
1) Understanding the interaction between hydrologic, climate and ecological processes from the perspective of water as the common agent that links these components.
2) Understanding how impacts in the environmental system derived from natural or economic activity are propragated.
3) Developing advanced predictive and analysis tools that can be used to inform policy and decision making in agricultural regions.
