Ricki Lewis has built an eclectic career in communicating the excitement of genetics.

David Shier has more than thirty years of experience teaching anatomy and physiology, primarily to premedical, nursing, dental, and allied health students. He has effectively incorporated his extensive teaching experience into another student-friendly revision of Hole’s Essentials of Human Anatomy and Physiology and Hole’s Human Anatomy and Physiology. His interest in physiology and teaching began with a job as a research assistant at Harvard Medical School from 1976-1979. He completed his Ph.D. at the University of Michigan in 1984, and served on the faculty of the Medical College of Ohio from 1985-1989. He began teaching at Washtenaw Community College in 1990. David has recent experience in online course delivery, including recording lectures for so-called “flipped” classrooms. He has also been interested in the relationship between pedagogy and assessment, and the use of tools traditionally associated with assessment (e.g. lab quizzes) as pedagogical tools, often associated with group activities.
