Department of Earth System Science

The UCI Department of Earth System Science (ESS) was the first in the nation established to quantify changes to our environment and discover ways we can adapt. Research in ESS focuses on how the atmosphere, land and oceans interact as a system and how the Earth will change over a human lifetime. ESS faculty research interests vary widely from climate, atmospheric chemistry, and biogeochemistry to oceanography and hydrology. The department ranks among the top in U.S. universities for the impact of its publications in geosciences. In addition to their research, faculty work to inform and educate policy makers and the community at large on a range of issues affecting the environment and quality of life.

Department of Physics & Astronomy

Physics lies at the forefront of our understanding of nature. It includes the study of the universe on the largest scales — astronomy and cosmology, and on the smallest —the physics of quarks and leptons. In addition, physics provides the background for high-technology; lasers, nuclear power, semiconductors, and medical imaging, all have their roots in physics. At the UCI Department of Physics & Astronomy, world-renowned physicists study exciting topics like quantum mechanics, gravitation, the big bang, black holes, magnetism, and superconductivity.
