Research Areas:

My work focuses on below-ground systems of urban forests and how they affect ecosystem service provision. My lab address a variety of contemporary challenges faced by cities in managing their urban forests. Particular interests are stormwater management as mediated by the below-ground system, soil carbon, managing urban soils during land development, and manufactured, blended and engineered soils. As part of the soils technical committee for the Sustainable Sites Initiative (SITES®), I helped develop sustainability standards for soils during site development and my research program emphasizes linking design and policy decisions to below-ground ecological processes to solve urban problems. I enjoy working closely cities and private practice to help address the many challenges of the urban environment.
