The biology faculty at WWU are committed Seventh-day Adventist scientists and teachers who genuinely care about students. They love teaching science, and diligently pursue using the most effective learning strategies and introducing the latest scientific information in a meaningful context. They also “practice what they preach” by staying engaged in the science community: regularly participating in science conferences, publishing research, and obtaining external grants.
