D.Env. in Environmental Science and Engineering

Master problem solvers

The next generation of master environmental problem solvers are trained here. Our academically diverse, practice-intensive method prepares graduates to take on today’s most complex environmental problems. The Environmental Science and Engineering professional doctorate was founded by Nobel laureate Willard Libby in 1973. Since then, more than 260 graduates have gone on to take senior leadership positions at places such as the Environmental Protection Agency, the Walt Disney Company, the Army Corps of Engineers and AECOM.

ESE Residency

The residency embeds students with public agencies, businesses and environmental groups to provide practical experience in environmental analysis and management. While students work, they conduct applied dissertation research under the supervision of UCLA faculty.

How UCLA ESE shaped my career

The UCLA Environmental Science and Engineering (ESE) program gave me a systems-based perspective on water resources and sustainability. It strengthened my ability to integrate science, engineering, and policy to design solutions that protect water quality and support climate-resilient communities


“As an ecologist with ties from farmlands in El Salvador to L.A.’s large urban ecosystem, the best way to protect habitats I love is integrating science and policy”
