Additionally, during this time, Dr. Hisley continued his interest in the application of imaging and analysis to anatomical education effectiveness in the Medical School and Radiology Department. His work here involved the contrast and comparison of knowledge types gained from physical dissection vs. digital dissection. This led to potentially-new techniques for improving the role of digital dissection within standard first-year.
Dr. Hisley taught at two DO medical schools from 2007 to 2015 before coming to William Carey University College of Osteopathic Medicine in 2015. At Des Moines University as an Assistant Professor, taught gross anatomy, neuroanatomy and embryology, and medical imaging.

He also collaborated actively with the Virtual Reality Applications Center (VRAC) at Iowa State University on immersive projects dealing with anatomical identification. Finally, at DMU, he designed a system for linking simulated auscultation exercises with anatomical viewpoints in real-time for first- and second-year students and submitted a patent application for this idea. At Touro University-California as an Associate professor, he developed methods for the integration of imaging, including ultrasound, into the dissection laboratory experience. He also continued his work in dissection laboratory progress tracking.
At William Carey, Dr. Hisley is continuing his work teaching the anatomical sciences for both clinical and pre-clinical students, including his role as Course Director of Anatomy in the Masters of Biomedical Sciences program.
