Research Interests: 

Brian Enquist's lab investigates how functional constraints at the level of the individual (anatomical and physiological) influence larger scale ecological and evolutionary patterns. He is broadly trained plant ecologist. His lab uses both theoretical, computational, biophysical and physiological approaches to address integrative questions related to (1) the evolution of form and functional diversity; (2) the origin of allometric relationships (how characteristics of organisms change with their size) and the scaling of biological processes - 'from cells to ecosystems'; (3) the evolution of life-history and allocation strategies; and (4) community ecology and macroecology. His research also includes the monitoring of long-term dynamics of growth and change within a tropical forest in the Area de Conservation, Guanacaste, Costa Rica.
