Engineering (MS)

Joint degree with the Yale School of Engineering and Applied Science (SEAS)

On This Page

    Program Overview

    The joint-degree program equips environmental engineers and environmental managers with the skills and experience needed to address the complex relationship between technology and the environment. Resource depletion, climate change, biodiversity, disease, food supply, and energy are critical societal challenges for the 21st century. Students in the joint program will be well prepared to design and manage engineered and natural systems that address these societal challenges, while considering the complex technical, economic, and sociopolitical systems relationships. 


    Students in the 2 ½ year joint program earn one of two environment degrees: a Master of Environmental Management (MEM) or the Master of Environmental Science (MESc) from the Yale School of the Environment (YSE), and a Master of Science in Engineering (MS) from the School of Engineering and Applied Science (SEAS). The program length, while atypical, offers several competitive advantages for graduates’ marketability. Students graduating in December will enter a job market with less competition given the significantly fewer degrees granted on this cycle.

    Course Requirements The joint MEM-MS degree program requires completion of 60 credits (as defined by Yale YSE system) or 20 courses (as defined by the Yale Graduate School of Arts and Sciences ,GSAS, system) as well as a summer internship and capstone project. The joint MESc-MS degree program requires 60 credits (as defined by Yale YSE system) or 20 courses (as defined by the Yale Graduate School system), with Thesis Research comprising at least 12 credits (equivalent to 4 courses), as well as completion of a Master’s Thesis.

    The following six courses are required of all joint-degree YSE/SEAS master’s students completing their M.S. in Environmental Engineering: ENAS 641, ENAS 642, ENAS 660, ENV 773, ENV 838, and either ENV 712 or ENV 724. Two additional Yale-wide technical electives approved by the DGS (or faculty in an equivalent role in Environmental Engineering) are also required for the M.S. in Environmental Engineering. For MEM or MESc program requirements courses, visit YSE’s master’s programs page.

    In addition, all joint-degree students are required to attend two weeks of technical skills training (“MODs”) before beginning their studies at YSE. These are hands-on workshops, offered every August, that teach plant identification, ecosystems management, land measurement, and urban ecosystem analysis as well as professional skills, including diversity and inclusion training, quantitative data analysis, data visualization, and environmental communication.

    Pathway Options

    Students may begin their studies at the School of the Environment (YSE) or at the School of Engineering and Applied Science (SEAS).

      Begin at YSE Begin at SEAS
    Semester 1 & 2 YSE SEAS
    Summer 1 YSE Internship/Research  
    Semester 3 & 4 SEAS  YSE
    Summer 2   YSE Internship/Research
    Semester 5 YSE YSE



    As with other joint master’s degree programs, students will be required to be independently admitted to both Yale units. Admission to both can occur prior to entry, or admission to a second unit can be applied for during the first year of residence in either program. YSE Admissions | SEAS Admissions

    Financial Aid

    Students pay tuition for three semesters at YSE, and two semesters at the School of Engineering and Applied Sciences. For more information on applying for financial aid at YSE, please see the YSE financial aid web page. For information on financial aid at SEAS, please see the SEAS (GSAS) financial aid web page. Students must apply for financial aid at each school, and any aid awarded will apply to the semesters in which a student is enrolled at that particular school.
