Our program's mission is centered on developing leaders who use their skills to promote social justice and societal and organizational change. Drawing on the Jesuit tradition of Creighton University and Jesuit ideals of academic excellence, respect for human dignity, and a faith that does justice, the program is built on a leadership model that encourages continual, critical self-reflection. With increasing self-knowledge, leaders are empowered to work mindfully toward a more just community, workplace, and world.
The concept of leaders as stewards of an organization is emphasized during each course and promoted through research activities. Program faculty and students come from a variety of disciplines and professions, and as such, provide a rich interdisciplinary learning community for understanding the nature and role of interdisciplinary work in today's world.
The mission is carried out and fulfilled by attention to the following programmatic themes. These themes describe the leaders the program strives to develop:
- Leaders who experience, appreciate, and are prepared to pursue integrative learning in a collaborative community of practice.
- Leaders who possess moral courage and skills to innovate, adapt, and act in a changing world, striving for a more just society.
- Leaders who develop professionally through a process of formation using continual self-reflection.
- Leaders who understand the organizational and systematic challenges and opportunities in interdisciplinary work and practice.
Upon completion of the Doctor of Education (Ed.D.) in Interdisciplinary Leadership Program, using an interdisciplinary perspective, students will:
- Utilize leadership theories and models to inform practice.
- Integrate critical thinking to inform professional leadership issues.
- Practice ethical decision making informed by Ignatian values.
- Model professional communication in scholarly and professional studies.
- Apply reflective practices as a means for professional and personal growth.
- Demonstrate the capacity for effective leadership within complex and diverse societies

On-Campus Dissertation Research Track
The Doctoral Program in Interdisciplinary Leadership is available as a fully online degree program. However, there is an option for students to complete their dissertation research on Creighton's campus in Omaha. Students must formally select this on-campus dissertation track either a) during on campus orientation held at the end of the first term, or b) prior to the beginning of the last 3 credit hour course taken immediately preceding dissertation hours. If a student is currently in dissertation hours, they are not eligible to shift into the on-campus track.
Students who meet all of the following criteria are eligible to apply for the on-campus dissertation track:
- Students do not have the academic resources in their home city or region to effectively complete their research.
- Students must have completed required online classes—core courses, research courses, research elective, and the proposal construction course.
- Students must have successfully achieved candidacy and met all other requirements of the program.
- Students must use the 8 x ILD 899 “dissertation” hours and the final 2 credit ILD 810 dissertation defense course hours during the on-campus portion of their studies. Note that ILD 899e, the 1 credit online course taken in conjunction with the ILD 890 course DOES NOT count as a dissertation hour.
- Students must have a formal Dissertation Chair (selected prior to the ILD 814 proposal construction course) and either the chair or the second committee member MUST be a Creighton faculty member that lives in the Omaha area.
Students enrolled in the on-campus dissertation track must also comply with Creighton’s Doctor of Education (Ed.D.) in Interdisciplinary Leadership Program requirements regarding continuous enrollment. Students are subject to the same evaluation process employed for all students in the Ed.D. in Interdisciplinary Leadership Program and are subject to the policies of Graduate School and Creighton University that apply to all Creighton students.
The schedule for the use of these hours may vary depending on when a particular student may start using these hours.
Note: - This option may carry with it financial aid implications. Consult the Financial Aid office to determine how this may affect your financial aid package. - International students must obtain the proper permissions and Visa to participate in this process. Consult the Global Engagement Office to work through that process.
The Doctor of Education (Ed.D.) in Interdisciplinary Leadership Program consists of a minimum of 60 semester hours and a required master’s or equivalent professional degree. Students will tailor the dissertation to focus on their particular professional/workplace interests.
