Kenneth Hisley PhD
Dr. Kenneth Hisley has over 20 years of experience in the investigating and teaching the anatomical sciences. Dr. Hisley earned his MS in Anatomy in 1996 and his Ph.D. in Anatomy in 2000 from the University of Maryland, Baltimore, both from the Dental School there. His doctoral dissertation investigation, performed in the Department of Radiology in the UM School of Medicine, involved the application of cardiac-gated magnetic resonance imaging to characterizing the morphology and hemodynamics of the human carotid bifurcation as potential diagnostic signs of blood flow pulsatility – one cause of plaque accumulation.
After his receiving his Ph.D., Dr. Hisley remained in the Department of Radiology as an Assistant Professor until 2007, investigating the automatic detection and characterization of volumetric pathological lesions in the liver and brain using image analysis of CT and MRI image sets. He also taught basic and clinical anatomical imaging for the Dental School, the School of Physical Therapy and the Department of radiation Therapy. 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 set up a direct network link for clinical images to the Radiology Department of a major local hospital and assisted there in efforts to understand the clinical applications of fMRI. 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. His main academic mission at WCUCOM involves the comprehensive integration of medical imaging into the curriculum and the initiation of the Radiology Club.

Dr. Porter received his PhD with Dr. Mary Coyne, a physiological neuroendocrinologist at Louisiana State University Medical Center in 1973.
Dr. Porter progressed through the academic ranks at LSUHSC from Instructor of physiology in 1973 to Full Professor of Physiology and Medicine in 1994. He was also made Full Professor of Pharmacology and Neuroscience in the late 1990’s at LSUHSC and Adjunct Professor of Physiology at Tulane Medical School during this same time frame. Dr. Porter was appointed Professor Emeritus of Physiology at the LSUHSC in 2010 upon his retirement and still holds that distinction.
Dr. Porter taught physiology courses in nursing, dentistry, dental hygiene, medical physiology, and graduate endocrinology during his Career at LSUHSC. Likewise he has taught several disciplines of physiology and he has been course director of Nursing, Medical School Physiology, Graduate Endocrinology, Dental Physiology, Dental Hygiene Physiology, a Special Topics in Oral Physiology and others. Dr. Porter was asked to be an adjunct professor of physiology at Tulane Medical School. In this position he has taught summer endocrine classes at Tulane Medical School and he has also taught endocrine control lectures in Biomedical engineering on the main Campus of Tulane.
In research, he has been the mentor to students at all levels as they have trained in his research laboratory. Dr. Porter has personally served as major professor of numerous Ph.D. and Master’s students. In addition, he has served on over 53 Graduate Committees at LSUHSC. He has also mentored several Post-doctoral and resident fellows in medicine and dentistry and over 60 high school students, medical students, dental student and various other student volunteers in his laboratory during his career at LSUHSC.
Dr. Porter has always been active in the regulation of the pituitary adrenal axis as his research interest. In recent years this research interest has been focused on the abnormal regulation of this neuroendocrine axis in obesity and food intake.
Most recently he has been interested in the adrenal steroid, dehydroepiandrosterone (DHEA). This steroid is also produced by neurons in the brain as well as the adrenal gland and it is thus classified as a true neurosteroid. He has worked for 25 years with an obese rodent model, the obese Zucker rat. This animal model is an excellent model of human youth onset obesity. This model has been used extensively by Dr. Porter’s lab and other laboratories to emulate the abnormal neuroendocrine regulation downstream of leptin insensitivity in humans. This research has resulted in two invitations for plenary lectures at international congresses (international congress of steroids in Fukuoka Japan and the International Society of Neuropsychiatry in Cancun Mexico) in the past 8 years. Most recently he has been invited to give the prestigious Lancaster-Puckett lecture at his alma mater, Western Ky. University, 44 years post baccalaureate. This research has been well funded by the NIH, the American Heart Association, and the American Diabetes Association. Work on the neuroendocrine control of the hypothalamic pituitary adrenal axis as it relates to premature labor also led to the funding of one of six recent National March of Dimes (MOD) Grants awarded for the 2006-2010 grant cycle. Dr. Porter joined WCUCOM in 2010 as Professor of Physiology.
