for students wishing to conduct scientific research that contributes basic and applied knowledge. These highly individualized two-year degrees offer a deeper disciplinary focus on forest-related topics (MFS) or other environmental issues (MESc) through formalized training in the philosophy and practice of science. Training is provided through key courses in combination with extended research. Students in the MFS/MESc programs have the opportunity to develop critical research skills, pursue self-directed research, learn and practice grant-seeking strategies, and create a publication-ready master’s thesis to be presented to the broader Yale community.</p> <h2>Advisor Relationships</h2> <p>Faculty research advisors play a key role in the MFS/MESc program. In addition to overseeing their scientific research, advisors collaborate with students to design and approve their unique course of study. Faculty provide guidance in selecting courses to support the design, execution, and communication of students’ master’s research and align with students’ career goals. They also serve as a resource during the process of proposing and completing the master’s thesis.</p> <p><em>Note: Applicants should connect with potential advisors before applying to the program. When applying, applicants will be asked to submit the names of three faculty members with whom they are interested in working. Advisors will be selected from that submitted list upon admission to the program.</em></p> <p> </p> </div> </div> </div> </div> </div> <div class="initial-12 medium-4 cell"> <div class="sidebar-program-content"> <h3 class="small-text"><strong>Degree Awarded</strong></h3> <p><span style='display: inline;'>Master of Environmental Science or Master of Forest Science</span> — MESc or MFS</p> </div> <div class="sidebar-program-content"> <h3 class="small-text"><strong>Program Duration</strong></h3> <p>2 Years</p> </div> <div class="sidebar-program-content"> <h3 class="small-text"><strong>Required Credit Hours</strong></h3> <p>48 credits, with formal coursework comprising at least 24 credits</p> </div> </div> </div> </div> </section> <section id="why-choose-yse-" data-jump-nav-heading="Why choose YSE?" class="two-up global-spacing global-spacing--xlarge paragraph--default two-up--why-yse blue--dark topographic-map global-padding global-padding--xlarge"> <div class="section-heading text-margin-reset" > <div class="grid-container"> <div class="grid-x grid-margin-x"> <div class='initial-12 cell'> <h2 class="section-heading__heading oho-animate oho-animate-single">Why choose the Yale School of the Environment?</h2> </div> </div> </div> </div> <div class="grid-container"> <div class="grid-x grid-margin-x">  <div class="cell initial-12 medium-6 global-spacing--default"> <div class="card card--small card--two-up card--collapse" > <div class="card__media"> <figure class="global-spacing--small"> <div class="aspect-ratio-frame" style="--aspect-ratio: .56"> <img loading="lazy" src="/sites/default/files/styles/4x3z5_medium/public/content/images/4577/Why-YSE-Experiential-21.jpg?h=2fb7e8de&itok=wEp7W2p5" width="800" height="600" alt="Students on a field trip at a water treatment facility" class="image-style-_x3z5-medium" /> </div> </figure> </div> <div class="card__content"> <div class="card__content__inner"> <h3 class="serif">Experiential Learning</h3> <div class="global-spacing--xsmall"> <p><p>At YSE, education and training extend well beyond the classroom. Participate in our unique summer orientation program, MODs; travel widely for field research and internships; attend global conferences and climate talks such as the U.N.

Decisions on the timing for completion of the coursework credits are made by the student and research advisor. Courses may be distributed evenly over two years, or a greater course load may be carried in Year 1 to accommodate research-related travel and fieldwork in Year 2.</p> <p><em>Introduction to the MESc and MFS Degrees</em> (<a href="https://resources.environment.yale.edu/courses/detail/555">ENV 555</a>), is mandatory and a requirement for all incoming MESc/MFS students in their first Fall semester.

The goal of this class is to set expectations and discuss general strategies for a successful MESc/MFS experience.</p> <p>MESc/MFS students are required to complete <em>Qualitative Inquiry for the Human Sciences</em> (<a href="https://resources.environment.yale.edu/courses/detail/551">ENV 551</a>) or <em>Natural Science Research Methods</em> (<a href="https://resources.environment.yale.edu/courses/detail/550">ENV 550</a>) in their first semester. Another research methods course may be substituted for ENV 551 or  ENV 550 when appropriate and subject to approval of the research advisor.</p> <p>Students should work with their advisors to select their remaining courses that will support the design, execution, and communication of their Master’s research and that are consistent with their career goals. These courses may be drawn from YSE, as well as from other departments or schools within Yale. </p> <p><a class="btn" href="https://resources.environment.yale.edu/courses">YSE Course Listings</a></p> </div> </div> </div> </div> </section> <section id="research" data-jump-nav-heading="Research" class="flexible-wysiwyg global-spacing global-spacing--xlarge global-padding global-padding--xlarge" > <div class="grid-container"> <div class="grid-x grid-margin-x"> <div class="cell medium-10 medium-offset-1 large-8 large-offset-2"> <div class="wysiwyg wysiwyg--full wysiwyg-column--center"> <h2>Research</h2> <h3>1. Thesis Research Credits</h3> <p>MESc/MFS students must also complete at least 12 credits of Thesis Research. Students may register for a maximum of six credits per semester of Thesis Research during their first year and up to 12 credits per semester in their second year, provided the 24-credit coursework requirement is satisfied. Thesis Research is graded as Credit/Fail and culminates with the Master’s Thesis.</p> <h3>2. The Master’s Thesis</h3> <p>The Master’s Thesis should be a coherent piece of scholarship in the form of one or more major papers suitable for publication in a peer-reviewed journal or as a chapter in an edited book. A Master’s Thesis typically includes original data or an original analysis of published data and leads to novel interpretations and new findings. The thesis should draw from research that begins and is carefully planned in Year 1. The research should be sustained through the summer and serve as a focus of student effort in Year 2.</p> <h3>3. Thesis Requirements</h3> <p>The thesis requirements consist of a research proposal and the thesis itself. The purpose of the proposal is to demonstrate that the study has scientific merit, the research plan is tractable, the methods are appropriate, and the results will likely represent a meaningful contribution to the scientific community. The proposal serves as a formal mechanism by which students can gain feedback on their progress, learn of potential pitfalls and problems, and receive counsel on requisite modifications to the research plan. The proposal should be submitted for committee review no later than 30 September in Year 2.  In some cases, advisors may require students intending to begin research over the Summer between Years 1 and 2 to have a completed proposal by the end of the second term in Year 1.</p> <p>The thesis should be completed by the end of Year 2. Meeting this timeframe relies on the conscientiousness and vigilance of the students and their advisors.
