Dr. Delius earned his B.S. in Integrative Biology from the University of Florida, where he concentrated in elasmobranch anatomy and physiology while working in the Ichthyology Department and the International Shark Attack File at the Florida Museum of Natural History. He earned his M.S. in Biology at Florida International University, where he studied consumer mediated nutrient transport and stable isotope biogeochemistry using bull sharks (C. leucas) as a model in the Florida Costal Everglades.  Dr. Delius then worked as an environmental consultant for eight years, focusing on wetland and wildlife permitting.  After which, he returned to academia and earned his Ph.D. in Integrative Biology at the University of South Florida where he studied the impacts of agrochemicals on wetland flora and fauna and zoonotic disease systems.

Dr. Delius is currently focused on science education and mentoring at Duquesne, teaching a variety of courses. His teaching philosophy centers on employing his practical field and lab research background to help students understand course material in the context of real-world science and incorporating active learning strategies and authentic problem solving into biology and ecology courses. He has extensive experience teaching a wide variety of undergraduate STEM courses to both majors and non-majors, and he is passionate about creating equitable learning experiences that are based on the best available scientific evidence.
