The program is full-time and requires in-person attendance. In their first semester students complete a set of foundational courses on computational design, scripting for automated drawing and modeling tasks, building systems analysis, and empirical inquiry to support design. They are also given a practical introduction to the conduct of research through a research colloquium. They begin focused study in their concentration area in the second semester, completing a course on the logic of inquiry, and taking advanced coursework of their own choice under the guidance of their advisors. This phase of study must include at least three credits earned for work on applied design problems; these credits may be earned either through work in one of the school labs, or as participants in design and research studios. Students typically select from the defined concentration areas listed above, but they may develop their own concentrations under guidance from their advisors and with program approval. To graduate, students submit a master’s thesis on a topic of their choice, completing at least 6 credit hours of work.

The concentration electives listed at the link above may not be offered each year. At the beginning of each academic year, the school releases a list of courses scheduled to be offered for the year. Students may substitute any of the courses listed here for electives of their choice, subject to program approval.
