He began his scientific career as a plant breeder, studying genetics, agronomy and agricultural ecology while completing his PhD at the University of Minnesota, and then spent several years at the University of Puerto Rico, investigating disease resistance and harvest quality in vegetables and dry beans. That introduction to the study of disease led Dave to the Fox Chase Cancer Center in Philadelphia, where he combined his interests in botany and medicine by studying tropical plants with potential antiviral effects.&nbsp; Joining the faculty at Eastern University (Pennsylvania) in 1992, Dave was soon teaching not only core courses in science like ecology, but adding electives like Medical Botany and Tropical Biology. He has taught Au Sable&rsquo;s Tropical Agriculture and Missions course in Costa Rica since 2003.</p>
