Integrated and Applied Sciences, Ph.D.

Saint Louis University's Integrated and Applied Sciences (IAS) doctoral program, offered in the Doisy College of Health Sciences, exposes students to all areas of science, encourages collaboration across departments and colleges, and better trains graduate students to present their research to a more diverse audience.

Program Highlights

Saint Louis University's Integrated and Applied Sciences doctoral program prepares students to become scholars and researchers in academic, clinical research, and/or practice settings. It allows students to pair their areas of study with interdisciplinary courses in biological, behavioral, psychosocial and environmental aspects of human health.

Students specialize in a health sciences discipline content area that aligns with the research being conducted by their faculty mentor. Currently available areas of study are:

  • Athletic Training
  • Clinical Health Sciences
  • Nutrition and Dietetics
  • Occupational Science and Occupational Therapy
  • Physical Therapy
  • Speech, Language and Hearing Sciences

Curriculum Overview
SLU's Doctor of Philosophy in Integrated and Applied Sciences program utilizes interdisciplinary approaches and collaboration to prepare graduates to confidently assume multi-faceted roles in the changing health care environment. 

The distribution of courses is determined on an individual basis. The student and their faculty mentor develop an appropriate coursework track with subsequent review by and feedback from the IAS administrative committee. A typical coursework structure is detailed below. To review the research being done in the Doisy College of Health Sciences, please visit our research page.

  • Research Courses (6 credits)
  • Courses specific to the student's Program of Study (21 credits)
  • Directed Independent Study (1 credit)
  • Required Course (2 credits)
  • Dissertation credits (12 credits)


This research-intensive doctoral program trains students for careers in pharmaceutical, health care, and biochemical industries, as well as in academia.
