David Poister

Professor of Chemistry and Environmental Science

David Poister is a professor of chemistry and environmental science at St. Norbert College, where he has taught since 1995. He is an environmental chemist with interests in biogeochemistry and the chemical ecology of aquatic systems. His current scientific research focuses on chemical interactions between algae and pigment formation in senescent tree leaves. In addition to his work as a scientist and SNC faculty member, Poister is interested in exploring how the dialogue between science and religion can be used to understand and advance the human condition.
