Julie Persellin, Ph.D.

Chair, Accounting

Director, Master of Science in Accounting Program

Photo of Julie PersellinMy professional career began as an auditor in public accounting for one of the large international firms. It was an incredibly valuable learning experience that sparked my desire to educate myself further regarding the complexities of the financial accounting world. While in graduate school, I had the opportunity to serve as a teaching assistant for an undergraduate auditing course. That experience would prove to shape the trajectory of my professional career. I have been teaching for over 20 years, and still look forward to the new faces, as well as the challenges that each semester brings.

Bringing structure out of chaos, both in terms of teaching and my research, is a cornerstone of what I do as an academician. I encourage students to embrace the notion of inquiry as that is the foundation of learning. Having a sound base and structure allows us to think and be constructively creative.
