Emeritus Faculty Profile

Rick Ridgway

Rick Ridgway

Associate Professor of Biology Emeritus

Email: rridgway@spu.edu

Education: BS, Biology, Seattle Pacific University, 1977; Secondary Teaching Certificate, Seattle Pacific University, 1978; MS, Washington State University, 1983; PhD, Washington State University, 1988. At SPU 1978–80; and since 1991.

Rick Ridgway’s research focuses on cellular biology, using primarily invertebrate animals for studies of nervous system regeneration and immune system function that serve as model systems for mammalian neural disorders, such as Parkinson’s disease, Alzheimer’s disease, and amyotrophic lateral sclerosis (ALS).

The techniques Dr. Ridgway employs in these studies include primary cell culture, electrophysiology, signal transduction assays, immunoassays, transmission and scanning electron microscopy (TEM/SEM), various forms of light microscopy, and confocal fluorescence microscopy.

He also collaborates with many other researchers, most recently with Dr. Tim Nelson in investigating anti-herbivore molecules produced by marine macroalgae that contribute to harmful “green tides” in the waters of Puget Sound.

Dr. Ridgway and students in his Freshwater Biology (BIO 4880) course, held at Blakely Island Field Station, were featured in the Autumn 2017 issue of Response.

Why I Taught at SPU

Rick Ridgway, Associate Professor of Biology Emeritus

I taught at SPU because I am so enriched by the enthusiasm for learning and the desire to serve others. I was raised in Seattle, but heard of SPU only after several Campus Life-Youth for Christ friends suggested I might be happier at a smaller college after expressing my frustration with the large and fairly impersonal classes I was experiencing at a large state university. After transferring to SPU, I got to know professors who cared about my growth both as a scholar and as a Christian. Later, upon completing graduate school and several years as a post-doctoral research fellow, I received an invitation to come back to SPU. I felt a very strong calling to return to the SPU community and share my joy of learning with new generations of undergraduate students through teaching, scientific research, and advising.
