Integrated and Applied Sciences, Ph.D.

Saint Louis University's Integrated and Applied Sciences (IAS) doctoral program was established to broaden student exposure to all areas of science, encourage collaboration across departments and colleges, and better train graduate students to present their research to a more diverse audience.

Program Highlights

The Health Sciences concentration prepares students to become scholars and researchers within academic, clinical research, and practice settings by conducting interdisciplinary studies of biological, behavioral, psychosocial and environmental aspects of human health. Required courses are taken in Doisy College of Health Sciences.

Curriculum Overview

Saint Louis University's Doctor of Philosophy in Integrated and Applied Sciences (IAS) utilizes interdisciplinary approaches and collaboration within the fields to prepare graduates to confidently assume multi-faceted roles in the changing scientific community. 

The distribution of courses in the various IAS areas is determined by the student’s dissertation committee with a minimum total of 30 credits between all three areas. A total of 42 credits are required with the remaining 12 credits coming from dissertation credits. An appropriate coursework track is developed by the student and their mentor with subsequent approval by the IAS administrative committee. A typical coursework structure includes:

  • Participating departmental core courses (9–12 credits)
  • Interdisciplinary credits (18–21 credits)
  • Dissertation credits (12 credits)

Fieldwork and Research Opportunities

This research-intensive doctoral program will train students for careers in pharmaceutical and biochemical industries, as well as in academia. The program’s scientific training takes place in an interdisciplinary environment with biology, biomedical science, chemistry, earth and atmospheric science, engineering, health sciences, and physics faculty.


This doctoral program trains scientists for careers in academia in health sciences and prepares them to collaborate with other professionals. Scientific training takes place in an interdisciplinary environment with faculty from science departments in SLU's College of Arts and Sciences, School for Science and Engineering and Doisy College of Health Sciences.

Admission Requirements

The integrated and applied sciences administrative committee will ensure that the applicant possesses a minimum of a baccalaureate degree from an accredited, recognized college or university in a discipline relevant to the research of the integrated and applied sciences faculty mentor.

Application Requirements

  • Application form and fee
  • Transcript(s)
  • Three letters of recommendation
  • Curriculum vitae
  • Professional goals statement

Requirements for International Students

All admission policies and requirements for domestic students apply to international students. International students must also meet the following additional requirements:

  • Demonstrate English Language Proficiency
  • Financial documents are required to complete an application for admission and be reviewed for admission and merit scholarships. 
  • Proof of financial support that must include:
    • A letter of financial support from the person(s) or sponsoring agency funding the student's time at Saint Louis University
    • A letter from the sponsor's bank verifying that the funds are available and will be so for the duration of the student's study at the University
  • Academic records, in English translation, of students who have undertaken postsecondary studies outside the United States must include:
    • Courses taken and/or lectures attended
    • Practical laboratory work
    • The maximum and minimum grades attainable
    • The grades earned or the results of all end-of-term examinations
    • Any honors or degrees received.

WES and ECE transcripts are accepted.

Review Process

The integrated and applied sciences administrative committee will ensure that the applicant's previous academic record indicates the ability needed to pursue advanced studies. The committee will then make an admissions recommendation to the graduate admissions department, which is responsible for making the final decision and communicating that decision to both the integrated and applied sciences program director and the applicant.

Scholarships, Assistantships and Financial Aid

For priority consideration for a graduate assistantship, apply by the program admission deadlines listed. Fellowships and assistantships provide a stipend and may include health insurance and a tuition scholarship for the duration of the award.

  1. Graduates will be able to use scientific principles underpinning the primary scientific discipline in which their concentration is based and by applying basic research methodology, demonstrate their application to their particular field of interest (chemistry, biology, physics, environmental science, sustainability science).
  2. Graduates will be able to demonstrate advanced creativity in scientific research methodology in their concentration and appropriately use techniques in a laboratory and/or field setting – including experimental, theoretical, and computational methods.
  3. Graduates will be able to integrate methods, theories, paradigms, concepts etc. from more than one discipline.
  4. Graduates will be able to demonstrate an ability to communicate (oral and written) results and conclusions from their research, describe techniques and methodology used, and apply their experiences in the greater world in which we live.
