Michael P. McKinley received his undergraduate degree from the University of California, and both M.S. and Ph.D. degrees from Arizona State University. In 1978, as a postdoctoral fellow at the University of California at San Francisco (UCSF) Medical School, he investigated prion-diseases. In 1980, he joined the anatomy faculty at the UCSF Medical School, where he taught medical histology and authored or co-authored more than 80 scientific papers. Joining the biology faculty at Glendale Community College from 1991 to 2012, Michael taught undergraduate anatomy and physiology, general biology, and genetics. Between 1991 and 2000, he researched Alzheimer's disease while teaching developmental biology and human genetics at Arizona State University, West. His vast experience in histology, neuroanatomy, and cell biology greatly shaped the content in Anatomy and Physiology. Retiring from active teaching in 2012, he continues to be an active member of the Human Anatomy and Physiology Society (HAPS). Valerie Dean O'Loughlin received her undergraduate degree from the College of William and Mary, and her Ph.D. in biological anthropology from Indiana University. She is an Associate Professor of Anatomy at Indiana University School of Medicine, where she teaches human gross anatomy to medical students, basic human anatomy to undergraduates, and human anatomy for medical imaging evaluation to undergraduate and graduate students. She also teaches a pedagogical methods course and mentors M.S. and Ph.D. students pursuing anatomy education research. She is active in the American Association of Anatomists (AAA) and the Society for Ultrasound in Medical Education (SUSME). She currently serves as President of the Human Anatomy and Physiology Society (HAPS). She received the AAA Basmajian Award for excellence in teaching gross anatomy and outstanding accomplishments in scholarship in education Theresa Stouter Bidle received her undergraduate degree from Rutgers University, her M.S. degree in biomedical science from Hood College in Maryland, and has completed additional graduate coursework in genetics at the National Institutes of Health and in science education at the University of Maryland. She is a professor at Hagerstown Community College, where she teaches anatomy and physiology and nutrition to pre-allied health students. She also mentors new full-time and adjunct faculty who teach anatomy and physiology. Before joining the faculty in 1990, she was the coordinator of the Science Learning Center, where she developed study materials and a tutoring program for students enrolled in science classes. Terri has been a developmental reviewer, has written supplemental materials for both textbooks and lab manuals, and is co-author of Eckel/Ross/Bidle, Anatomy and Physiology Laboratory Manual, 3rd edition.
