My work focuses on below-ground systems of urban forests and how they affect ecosystem service provision. This focus allows me to 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. I have a long-standing interest in linking design and ecological processes to solve urban problems and my teaching and research reflect this interest. I enjoy working closely cities and private practice to help address the many challenges of the urban environment.
