Research Interests
Plant phylogenetics; conceptual issues in evolution and systematics; origin of life
David Baum

My overarching research goal is to understand how evolution works to generate the remarkable diversity of living organisms around us today. In addition to various theoretical and conceptual interests, I have conducted research in diverse areas of plant evolutionary-developmental biology, plant phylogeny, and molecular evolution.  A major current focus is empirical and theoretical research on the origins of life.

At the introductory level I teach in Introductory Biology (Bot/Bio/Zoo 151) and frequently teach evolutionary biology courses at various levels from a Freshman Interest Group to a graduate, primary literature-based course, Foundations of Evolution (Bot 820). I commonly contribute to the teaching of Seminars in Plant Systematics and Evolution of Astrobiology.
