Speaker Bios

Lance Butler is a Senior Scientist at the Philadelphia Water Department’s Office of Watersheds. He is currently pursuing his PhD in Environmental Science at Drexel University, focusing on restoration ecology and bioremediation in aquatic ecosystems. Presently, his work has been focused on freshwater mussel restoration and the evaluation of ecosystem services provided by bivalve communities in urban-centric environments. Since 2001, he has also been involved in planning, design and monitoring programs associated with the Flatrock DamManayunk Canal Improvements Project. Recently, he was involved in the development and implementation of the Aquatic Research and Restoration Center (ARRC), a multi-agency cooperative aimed at restoring and enhancing aquatic ecosystems in the urban portions of the Delaware Basin.

Danielle Kreeger, Ph.D., is an ecologist with more than 35 years of experience working as a research scientist and educator. She currently serves as Senior Science Director for the Partnership for the Delaware Estuary (PDE), where she represents the National Estuary Program’s scientific interests by crafting, leading and participating in collaborative science and technical teams that address the goals set forth by the organization’s Comprehensive Conservation and Management Plan. For example, she was the main architect of the Mid-Atlantic Coastal Wetland Assessment, Delaware Estuary Living Shoreline Initiative, Freshwater Mussel Recovery Program, Technical Report for the Delaware Estuary and Basin, and biennial Delaware Estuary Science and Environmental Summit. She coordinates the estuary’s Science and Technical Advisory Committee. In addition to her work for PDE, Danielle also maintains an appointment as an associate research professor at The Academy of Natural Sciences of Drexel University.

Maitreyi Roy serves as Executive Director for Bartram’s Garden, home of famed 18th century botanist John Bartram (1699-1777). Today the 45 acre landscape is a National Historic Landmark on the tidal Schuylkill River, once the ancestral lands of the indigenous Lenni Lenape, and a public space resource operated in partnership with the City of Philadelphia. Since 2012, Maitreyi has worked with the board, staff and community leaders to restore and transform Bartram’s Garden as a historic and cultural asset, advancing an ambitious strategic action plan and establishing the Garden as a vibrant civic commons and outdoor living room and class space for the Southwest Philadelphia community. Trained as an architect in India, Maitreyi’s interest in open space issues took her to the Design School at Harvard University where she earned a master’s degree in Landscape Architecture.

Bria Wimberly is an Environmental Educator at the Audubon Mid-Atlantic located in The Discovery Center. Born and raised in West Philadelphia, Bria found her interest in environmental science when visiting Cobbs Creek as a child. She received her BS in Marine Biology from Florida International University in 2015, then moved back to Philadelphia to teach what she learned. She spent five years working as an educator and coordinator for Fairmount Water Works focusing on aquatic macroinvertebrates and the outreach program for their freshwater mussel hatchery. As of January 2020, Bria has joined the Audubon team as an Environmental Educator teaching neighborhood children about the importance of our watersheds, conservation, ecosystems, and everything in between.

Stacey Heffernan has an MS in Biology and an MA in Education and is currently an Environmental Educator for the Philadelphia Water Department at the Fairmount Water Works Interpretive Center. She develops and implements programs to engage audiences in activities that foster a greater appreciation for the urban watershed and a deeper understanding of our relationship to water. She especially loves to facilitate connections to the wonders of the natural world and to work with youth to encourage our next generation of stewards.
