Two Distinguished Departments Join Forces
We've evolved! Two very distinguished departments at the University of Arizona have dissolved their disciplinary boundaries to develop new and bold strategies to characterize, monitor, and model the hydrosphere. Our new vision is to lead the world in integrated and quantitative hydrologic and atmospheric sciences and to develop the knowledge needed to solve Earth's water, hydrogeologic, weather, and climate related problems. New collaborative opportunities in teaching and research will engage the entire community, from undergraduate students through senior faculty. Going forward in the 21st century, we embrace the need for both regional and global perspectives in climate change, water resources, and other environmental issues that affect society. We're looking for motivated students to help us pursue these goals. One thing is for certain: We’re better together.
