Speaker Information
Dexter focuses on actionable, transdisciplinary, team science and working with urban natural resource managers his passion. He has degrees in Natural Resources Planning (University of Vermont), Environmental Science (Yale School of Environment), and Geography (Clark University). His research focuses on the world’s fastest changing ecosystems, where the dominant species is Homo sapiens: urban ecosystems. He has growing interests in synthesis, meta-science, open data, reproducibility, and replication. When not studying urban forests or programming in R and Python, he can be found volunteering with urban forestry groups in Maryland where he lives.

Speaker Information
Dr Mark Bradford is the Professor of Soils and Ecosystem Ecology at the Yale School of the Environment. Bradford’s work focuses on the health, biology, ecology and carbon storage potential of forest, grassland and agricultural soils. He is interested in developing knowledge that allows us to predict how environmental change and management will affect the rates of carbon stabilization and decomposition processes, and hence how the size of soil organic carbon stores change in space and time. Since starting at Yale in 2009, Dr. Bradford has increasingly focused on practice-relevant issues, including experimental assessment of urban afforestation techniques as part of NYC’s Million Trees Initiative.
Dr. Bradford holds a BSc and PhD in Biological Sciences from Exeter University in the UK.

Cecil is passionate about using trees and nature to develop better cities, and always stresses the importance of building meaningful relationships between people and places. He has advised international organizations such as FAO, as well as national and local governments in more than 30 countries, and was an invited panelist at the 8th Ministerial Conference on the Protection of Forests in Europe in April 2021. Cecil currently lives in Barcelona from where he co-directs the Nature Based Solutions Institute, a think tank for the evidence-based greening of cities.

Speaker Information
Max Piana is a research ecologist at the USDA Forest Service, based in Amherst, MA. From street trees to urban forested natural areas, Max’s research integrates concepts of restoration and plant ecology to inform management and planning in cities. He currently co-leads the Urban Phytotechnology Project in Philadelphia and the Urban Silviculture Network, which spans eight cities in the northeast U.S. Max is an alum of Yale (MEM, ‘11) and URI and received his PhD in Ecology & Evolution from Rutgers University, where he was land manager of the Hutcheson Memorial Forest Center.

Speaker Information
Danica Doroski received her Ph.D. and M.F.S. from the Yale School of the Environment. She is currently the State Urban Forestry Coordinator at Connecticut’s Department of Energy and Environmental Protection. Prior to moving to Connecticut, Danica worked in New York City for the New York Restoration Project and the New York City Department of Parks and Recreation and in Philadelphia at the Morris Arboretum.

Speaker Information
Jennifer Greenfeld is the Assistant Commissioner of Forestry, Horticulture, and Natural Resources for the New York City Department of Parks & Recreation. In this role, she protects, restores, expands, and manages New York City’s urban forest, natural spaces and green infrastructure. Over the last 24 years at Parks, Jennifer led critical efforts to study the health and mortality of street trees and to quantify the impact of trees on the urban environment. She played an important role in MillionTreesNYC, initiated and implemented the agency’s transition to Tree Risk Management, and has overseen the restoration and management of thousands of acres of natural areas including the completion of the first fish passage in New York City, on the Bronx River; the restoration of salt marshes and the planting of over 550,000 trees, shrubs, perennials, and grasses as a part of this management.
Prior to working for New York City Parks, Jennifer worked on land conservation and urban forestry in San Francisco and Washington DC . She obtained a BA from the University of Pennsylvania, and a Master of Forest Science from the Yale School of Forestry & Environmental Studies.

Speaker Information
Professor Emeritus of the Departments of Landscape Architecture & Environmental Planning and Environmental Science, Policy and Management, UC Berkeley. During his 44 year career at the University of California he taught courses in ecological analysis, forest ecology, urban forestry, and California Landscapes. He currently teaches Urban Ecology and hydrology at the University of Navarra in Pamplona, Spain. His research has focused on various aspects of urban forestry as well as studies of forest succession. The urban forest research includes studies of the effects of trees on air pollution in urban areas, transition of wildland forest to urban forests, the influence of biome characteristics on urban forests around the world, the reconstruction of urban forest destroyed by warfare, and the impact of climate change on street trees in California. McBride received a B.S. in forestry from the University of Montana and M.S. (Forestry) and Ph.D. (Botany) degrees from the University of California, Berkeley.
