Lindley Darden is a philosopher of science and historian of biology, with a special interest in reasoning in the discovery of biological mechanisms. Her research focuses on reasoning strategies in scientific change, more specifically, reasoning in the discovery of biological mechanisms, strategies for evaluating mechanisms, and diagnosis and redesign of hypothesized mechanisms, given empirical anomalies. She uses biological cases from molecular biology, classical genetics, and evolutionary theory. Her next research project is in the history and philosophy of computational molecular biology.
