Biography

Lawren Sack is a Professor in the Department of Ecology and Evolutionary Biology at UCLA. His research broadly focuses on the mechanisms underlying the function and coexistence of plant species, particularly their responses to environmental challenges and resource availability, and the evolutionary functional consequences of this diversity. His team investigates processes at scales ranging from molecules to ecosystems, with current research exploring hydraulics in leaves and whole plants, the evolution of functional diversity in leaf designs, and scaling laws related to plant design and ontogeny. Additionally, they examine how plant physiology, ecohydrology, and competitive dynamics contribute to the interactions between native and invasive species in forest ecosystems, with implications for understanding species survival under changing climate conditions.
