Textile Engineering Science (PhD)

Program Director: Brian George, Ph.D.


The mission of the Textile Engineering and Science Doctor of Philosophy program is to educate textile engineers who combine theory, practice, scholarly research and application of knowledge in their chosen professions. It is expected that graduates of the doctoral program will pursue careers in basic and applied research in industry, government or university settings. Graduates will contribute original research and scholarly publications to the fiber and textile fields.

Program Learning Outcomes

Graduates of the Ph.D. in Textile Engineering will: 

  • Demonstrate knowledge of and proficiency in applying research methodology to textile engineering.
  • Demonstrate knowledge and proficiency in technical aspects of textile engineering.
  • Analyze and critique established textile and engineering theories and synthesize new theories based on research.
  • Apply their acquired skills toward the development of a unique research project.
  • Perform written and oral technical communications at a competent level.

Program Description

The doctoral program in textile engineering and science emphasizes not only depth in fundamental textile engineering and science/mechanical engineering disciplines, but also an interdisciplinary approach to understanding technologies in which textile engineers and scientists can and should take a leading role. It is this combined emphasis on fundamentals, the ability to think and work outside one’s area of expertise and the ability to frame complex problems that best defines this doctoral program. Students will propose a textile engineering and science problem of substance and then develop a solution. Students must demonstrate the ability to apply scientific principles to meet engineering needs with due regard to social and economic factors, and they must do so within a reasonable time constraint.

Program Structure

Doctoral candidates will have as their primary goal the completion of an original engineering/scientific contribution to the body of knowledge in the field of textiles. This contribution will be in the form of a written doctoral dissertation that will be defended in the presence of the faculty of Philadelphia University.

During the first year of the program, students will complete required coursework, including a 9-credit-hour (three courses) engineering minor. In a collaborative agreement with nearby Temple University, these graduate-level courses may be taken at the College of Engineering at Temple, or at another university after consultation between the student, the dissertation chair, and the director of the program.

All courses will be taken in the first year of the doctoral program. Students will then be required to pass a two-part qualifying examination in the field of textile engineering. The first part is a written examination, and the second part is an oral examination. A major and a minor topic will be chosen by the candidate and the doctoral committee and agreed upon at least four months in advance of the examination. Dates for the written and oral exams will be selected by mutual agreement of the candidate and the committee members.

All members of the committee should be present for the oral examination. The written examination may be administered by the committee chair with input from other committee members. The result of the two-part qualifying examination will be a pass or a fail. Both the written and oral examinations should be completed by the end of the second semester of study. Upon the successful completion of the examination, students will be formally admitted to doctoral candidacy. This will usually occur after the first year of full-time enrollment.

Students who fail the qualifying examination on the first attempt will be given one more chance, at the discretion of the committee, to improve their performance. In any case, the qualifying examination must be completed before the end of the second year of the student’s doctoral program.

The candidate will then make a formal Ph.D. thesis proposal defense. Once approved by the doctoral committee, students will conduct their doctoral research and subsequent dissertation. At the completion of a written dissertation, the candidate will give a formal and public thesis defense. Upon a successful defense, the student’s candidacy will be completed, and upon the recommendation of the faculty of the Philadelphia University the candidate will be awarded the Ph.D. in the field of textile engineering and science. 

Degree Requirements

Year 1 (18 Credits)

  • Selection of doctoral advisor
  • Completion of doctoral committee selection
  • Three engineering courses at Temple University  (9 credits)
  • TES-901                 Preliminary Examination Preparation   (3 credits)
  • TES-902                 Thesis I  (6 credits)
  • Successful completion of doctoral qualifying examination

Year 2 (18 Credits)

  • Doctoral thesis proposal defense
  • TES-903                 Dissertation Research I  (9 credits)
  • TES-904                 Dissertation Research II    (3 credits)
  • TES-906                 Thesis II  (6 credits)
  • Defense of Doctoral Dissertation

Credit for previous master’s degree: 36 credits (minimum)


While it is the intention to have students study full-time, there will be a provision for students to take a leave based on personal reasons. In all cases, students will have a maximum period of seven years from the date of initial enrollment to complete all doctoral degree requirements. The minimum time requirement to complete the doctoral program is two years. The minimum full-time enrollment in residence is two semesters.

Admission to the Ph.D. Program

The Ph.D. program in textile engineering and science is primarily an advanced research-oriented program that will be offered to selected graduates of M.S. Textile Engineering programs. Students from M.S. Textile Engineering programs that are offered internationally also will be considered for admission. Candidates with advanced engineering degrees in fields other than textiles, e.g., mechanical, chemical or materials, may be considered for admission if they agree to take master’s-level textile engineering courses at Philadelphia University. The credits they receive for these additional courses will not take the place of the required nine credits of minor courses in engineering, and they will serve as foundation-level courses.

Standardized Test Requirements

Applicants to the Ph.D. program who have master’s degrees in textile engineering (or other acceptable fields as noted above) from a university in the United States are not required to submit GRE or TOEFL scores for admission. For all other students (international students and those who do not have an acceptable master’s qualification) the requirements for the admission to the M.S. in Textile Engineering program will apply.

Graduate Research Assistantships

Students admitted to the Ph.D. in Textile Engineering and Science program will be offered research assistantships funded through external grants and contracts. The selection of students is based on the suitability of students’ backgrounds and their interests in fields that match those of the funding professor.
