Undergraduate Program

Environmental Science and Engineering (ESE) is an interdisciplinary program with the goal of understanding, predicting, and responding to natural and human-induced environmental change. Addressing environmental issues such as global warming, stratospheric ozone depletion, or local and regional air and water pollution requires perspectives from a diverse set of scientific disciplines including atmospheric physics and chemistry, oceanography, glaciology, hydrology, geophysics, ecology, and biogeochemistry. We view the environment as a complex set of chemical, physical, and biological interactions, made even more complicated by the various activities of human society.

Through exploration of the underlying processes and feedback within the Earth system, and with a range of approaches from theory and modeling to experiments and observations, we train students to think about environmental processes in an integrated fashion, preparing them to manage the environmental challenges we face.
