Biography

Julius Keller is an Assistant Professor in the School of Aviation and Transportation Technology at Purdue University. He is an active Certified Flight Instructor with airplane single- and multi-engine, and instrument-airplane ratings. Prior to entering academics, Dr. Keller gained experience as a charter pilot in a Piper Navajo. He also managed multi-modal transportation and logistics for numerous Fortune 500 Companies.

Dr. Keller’s primary scholarly areas include addressing issues identified by the FAA and NTSB such as fatigue among collegiate aviation pilots and wildlife strikes. Dr. Keller has also investigated VFR into IMC and safety culture. He intentionally uses research to promote effective teaching and learning for the purpose of improving pilot competencies as well as safety. His research has been acknowledged by the Federal Aviation Administration and the University Aviation Association.

In addition to his scholarship, he has been recognized for his leadership efforts involving women and underrepresented minorities in collegiate aviation. Dr. Keller is the faculty advisor for the Women in Aviation Purdue Chapter, the University Aviation Association, and Diversity Committee member with the Aviation Accreditation Board International.

Dr. Keller teaches courses pertaining to advanced transport operations, multi-cultural team operations, and research methods.
