The Yale School of the Environment (YSE) offers master’s degrees and doctoral programs and serves as a locus for research into local, regional and global environmental issues. Founded in 1900, YSE students establish close relationships with faculty mentors, work in well-equipped laboratories and use the resources of one of the world’s largest library systems. They choose from a broad selection of courses at YSE and at other graduate schools at Yale University, including the law school, the school of public health and the school of management. Students with well-defined cross-disciplinary interests can apply for joint degrees at nine different schools.
