Doctor of Philosophy in Interior Architecture and Environmental Design
Program Description:
The Department of Interior Architecture and Environmental Design offers a Ph.D. degree program with the possibility of specialization in building science, design theories and methods, environmental psychology and design, and history of interior architecture/architecture. Students are guided through an intensive program that emphasizes scholarly inquiry, research skills, analysis, and constructive criticism. The curriculum provides an interdisciplinary outlook, incorporating knowledge from related disciplines. The graduate studio combines theory and application. Elective courses are selected in consultation with an academic advisor.

Research Tracks:
Building Science
This research track deals with environmental quality in buildings. Interactions between occupants and environmental attributes like lighting, acoustics, and thermal comfort are examined to understand how well a building is performing. Lighting topics include daylighting, artificial lighting, and color. Acoustics topics cover room acoustics, building acoustics, and noise control. Thermal comfort topics comprise heat, bioclimatic comfort, HVAC (heating, ventilation, and air conditioning), energy efficiency, and condensation. Building materials, components, and subsystems are also covered, along with their impact on building performance.
Design Theories and Methods
This research track tries to answer questions such as: What is design? What is a design process? What type of knowledge do the designers use in the design process? What methods do the designers use in proposing alternative solutions? What methods and theories that are developed in other disciplines (education, social science, computer science, etc.) can be used in design? How can the quality of design education be improved? How are design ideas communicated and presented?
Design Theories and Methods, as an interdisciplinary area of study, seeks the theoretical background of design and the methods designers use to explore, generate, and develop alternative design solutions. The tools and techniques used in design practice are also investigated. A computer is a widely used tool in the design process and in data and knowledge representation. Therefore, current digital opportunities in design are also explored, such as collaborative design, virtual design environments, data modeling, and visualization.
Environmental Psychology and Design
This research track examines human interactions with(in) the built environment, and their implications for design. The concepts such as personal space, privacy, territoriality, and control are utilized in the analysis of human-space interaction. Spatial factors, which influence perception, cognition, and the resulting understandings and behavior, are studied at both individual and societal levels. Transformations in society and spaces are also covered to the extent of their impact on human behavior, particularly in public spaces.
History of Interior Architecture/ Architecture
This research track explores the history and theory of interior architecture, as well as the history of design and modern architecture as cultural, spatial, and interdisciplinary practices. It considers interiors as dynamic sites where identity, social relations, and changing cultural patterns are shaped and contested. Topics of study include museum studies, visuality, historic interiors, housing, dwelling, home-making practices, gender, urban and public interiors. Approaching ideology and the politics of space, research areas also encompass adaptive reuse, heritage, material histories, vernacular traditions vis-a-vis innovative craft technologies as ways of addressing contemporary spatial challenges.
Aims and Objectives:
The Ph.D. program in Interior Architecture and Environmental Design is a research program open to all candidates holding a Master’s Degree, that is structured to provide specialization in various areas that require expertise in the Interior Architecture and Environmental Design discipline, as well as scholarly inquiry and research skills. Students are guided through an intensive, focused program based primarily on educational objectives they have selected for themselves. By investigating pertinent past and current developments in the world and in Turkey within a cross-cultural framework, students examine various aspects of processes in design, implementation, performance, and evaluation to achieve the objective of producing work and demonstrating competence in research, interpretation, and assessment.
Admission:
Applicants are required to have a master’s and a Bachelor’s degree in a relevant field. Applicants should take the ALES (Akademik Personel ve Lisanüstü Eğitimi Giriş Sınavı, Academic Personnel and Postgraduate Education Entrance Examination) and must satisfy the announced minimum requirements. Applicants who are not Turkish citizens and Turkish citizens residing abroad may take the GRE (Graduate Record Examination) instead of the ALES. All non-native English speakers are required to submit proof of English-language proficiency. Admittance is also determined through an interview given before the beginning of each academic year. The University announces the date and place of the interview each year.
Degree Requirements:
The minimum course load for the Ph.D. program is 21 credit units. After completing the courses, the Ph.D. candidate must take a qualifying examination, give a presentation on his/her thesis, and submit a thesis proposal, which will be evaluated by a jury of well-known scholars in the relevant field. Upon a favorable jury evaluation, the candidate will qualify to work on a Ph.D. thesis. Upon completion of the thesis, a similar jury will examine the thesis and the candidate to reach a final decision on the degree. The duration for completing degree requirements is 8 semesters.
The typical course of study involves completing required coursework during the first year of the program. The course selection is subject to the approval of the Academic Committee. In the subsequent years, Ph.D. candidates register in IAED 690 Seminar in Advanced Research Topics (0 Credit / 6 ECTS) and/or IAED 699 Ph.D. Dissertation (0 Credit / 6 ECTS) for completion of the seminar and thesis requirements.
