Alan Gillen was born in Uniontown, Pennsylvania and lived there for 21 years.
Gillen started his work by assisting research in aquatic biology during 1967 and 1977. He received a Bachelors degree in Biology from the Washington & Jefferson College in 1978. For his graduate work, he moved to Ohio State University, publishing research in aquatic biology. He received his M. S. in Zoology from Ohio State in 1980.
From 1981-1984, Gillen worked as a graduate teaching assistant, instructing Preparatory Biology and Zoology. He then obtained a teaching certificate in Biology and Composite Science, teaching part-time while continuing his graduate studies at Baylor College of Medicine. He taught Honors Biology I and II, and Health as a science teacher in Worthing High School for 4 years, and was honored as a "Teacher of the Year" during 1986 and 1987. He then coordinated and taught science laboratory at the Shlenker School for 2 years. In 1990, he received an Ed. D. Science Education in Microbiology from the University of Houston.
From 1992 to 1996, Gillen taught research and development of cell biology and virology laboratory activities in the Microbiology & Immunology department of Baylor College of Medicine. While at Baylor, he helped develop the educational computer software applications MacSneeze™ and Common Cold Kit™ as tools for high school and junior college Biology instructors.
From 1997 to 2004, Gillen worked at Pensacola Christian College, primarily teaching, advising and working with Premed and Nursing students in Anatomy & Physiology, Microbiology, Parasitology, Professional Issues in Biology, General Biology (majors) and Survey of Biology (non majors).
Since 2004, Dr. Gillen has been on the teaching staff as a professor of biology at Liberty University. He has taught Human Anatomy and Physiology and is now teaching microbiology and biology seminar courses.
Dr. Gillen has also done considerable work editing and authoring biology textbooks for grade-school and college-level courses.
