I am an associate professor of philosophy at the University of Minnesota and director of the Minnesota Center for Philosophy of Science. My research focuses on conceptual issues in biology.
Much of my work has concentrated on the concepts of innovation and novelty in evolutionary developmental biology (Evo-devo). I also am interested in issues that arise in developmental biology and functional morphology. I use a combination of approaches to investigate a variety of philosophical questions: conceptual change, explanatory pluralism, the structure of evolutionary theory, reductionism, the nature of historical science, and interdisciplinary epistemology. Other areas of interest include the role of history in philosophical research and the nature of intuitions generated by thought experiments in philosophical inquiry.

Tree scorpions (Opisatacanthus asper) are about 100 mm long and live in bark crevices of large trees in Gorongosa National Park. They are dark brown to black in color, and usually camouflaged in normal light. However, when illuminated with ultraviolet light, they fluoresce in a bright turquoise color that’s easily visible—even during the day.
