Professor McPhearson studies ways to better design, restore, and build resilient and sustainable social-ecological systems. He focuses his research on understanding the linkages between urban ecological structure and function with a keen interest in the role of biodiversity and valuation of ecosystem services. Professor McPhearson’s research, teaching, and activism centers on the premise that humans are integrated components of ecosystems and therefore must recognize and take responsibility for the intimate role they play in the structuring and functioning of all ecosystems. This is nowhere more apparent than in urban areas. Cities are home to more than fifty percent of humanity and rising, which poses potentially dramatic implications for the well being of urban residents and the natural systems they depend on. The fact that most people’s experience of nature is urban suggests that cities need to become models of resilient and sustainable social-ecological systems. Accordingly, McPhearson’s research efforts are focused on better understanding urban socio-ecologies and protecting and restoring ecological functions and services in the urban systems.

Professor McPhearson’s research, from the lab to the field, aims to reveal and conserve the ecological processes that structure and maintain the biodiversity that underpins critical ecosystem services, functions, and structures in urban landscapes. To do this he explores the major environmental factors, both abiotic and biotic, that affect community dynamics and ecosystem function. His lab uses both empirical and theoretical approaches including mathematical modeling, spatial analysis, laboratory experiments, and field studies to enhance our understanding of urban ecosystems with the goal of developing best practices for enhancing urban resilience and sustainability. His research is primarily focused on four overlapping areas: (1) The economic and non-economic valuation of urban ecosystem services and associated biodiversity; (2) The influence of management and environmental stress on community structure and ecosystem functioning in urban ecosystems; (2) the relationship between environmental stewardship and ecosystem services; and (3) the relative importance of cooperative interaction and its effects on system dynamics.
