PhD in Earth & Environmental Sciences
Lehigh has a small, focused, field-oriented graduate program linked to nationally prominent research in some of the key areas of Earth-systems science. EES offers both the MS and Ph.D. degrees in Earth and Environmental Sciences. Under a broad Earth-systems umbrella, students do basic research in many of the subdisciplines of ecology, environmental science, geology, geochemistry, and geophysics. The Ph.D. requires additional credit hours (depending on your entry level), and of course a dissertation, on the road to which there are two exams designed to assess, respectively, your overall training, and your specialized expertise relevant to your dissertation proposal. Most Ph.D. theses in recent years have used a format in which the thesis chapters amount to papers submitted to or published in the peer-reviewed literature.
