- Restoration ecology research related to:
- identifying, developing, and using genetically diverse and appropriate native plant materials for restoration
- managing natural areas to support species diversity
- Research to support ex situ conservation of rare species that can't be seed banked
As Director of Restoration Ecology, I oversee the Garden's Department of Restoration Ecology and natural areas (including the amazing McDonald Woods, Dixon Prairie, Skokie River Corridor, Barbara Brown Nature Reserve, and Garden Lakes). My goal is to work collaboratively with land managers to harness the Garden's research capacity to address priority management needs. Ultimately, our goal is to play a leading role in supporting the conservation, management, and restoration of native plant diversity in the Chicago region that serves as a model for work in the United States and globally.
Much of my research is carried out with students as part of the Garden’s graduate program in Plant Biology and Conservation and Research Experiences for Undergraduates program.

Plant Conservation Alliance Non-Federal Cooperator Committee The Plant Conservation Alliance (PCA) is a public-private partnership of organizations that share the same goal: to protect native plants by ensuring that native plant populations and their communities are maintained, enhanced, and restored. PCA Non-Federal Cooperators include state agencies and private organizations interested in native plant conservation in the United States. The PCA Non-Federal Cooperator Committee (NFCC) partners with the PCA Federal Committee and others to advance plant conservation, promote native plant community restoration, and conduct plant conservation research. It represents the interests and ideas of Cooperator organizations and agencies, including botanic gardens, universities, educational groups, state agencies, businesses, professional societies, trade associations, native plant societies, and garden clubs. This Committee is chaired by the Chicago Botanic Garden. The NFCC works to advance plant conservation, native plant community restoration, and plant conservation research and advocacy at local, state, and national levels.
Botanic Gardens Conservation International Botanic Gardens Conservation International maintains information on plant conservation and education around the world, highlighting the important work of botanic gardens and partners in achieving the Global Strategy for Plant Conservation. From 2008 - 2013 I was Executive Director of BGCI in the United States and helped develop numerous projects in support of the Global Strategy for Plant Conservation, including ex situ conservation of exceptional species, botanical capacity in the United States, a North American assessment of ex situ collections, and developing conservation interpretation materials for public gardens.
Seeds of Success The national Seeds of Success program, established in 2001 by the Bureau of Land Management and the Royal Botanic Gardens Kew Millennium Seed Bank, is working to collect, conserve, and develop native plant materials for stabilizing, rehabilitating and restoring lands in the United States. Many botanic gardens, including the Chicago Botanic Garden, are partners on this nationwide project. I learned a lot about the power of partnership from this program, and am proud that my research helps inform its work.
Center for Plant Conservation's National Collection of Endangered Plants
As an endangered plant specialist, I managed a two-year, collaborative project (funded by the Institute of Museum and Library Services, or IMLS) to create CPC's National Collection of Endangered Plants website. This site outlines what the network of CPC-member botanic gardens are doing to help conserve more than 575 threatened and endangered plants in the United States, and details each species' current status, as well as management and research needs. This project was completed in December 2002, and the site is now hosted and continually updated on the Center for Plant Conservation's website. This project allowed me to interact with the wonderful network of researchers at botanic gardens around the country who are working to conserve the nation's imperiled plants, and also showed me the significant need for more research to help guide management decisions for these rarest of plants. This experience strongly influenced my decision to pursue my Ph.D. and conduct research with real on-the-ground applications.
Plants of Concern As a Garden intern, I worked with Garden scientists on research aimed at understanding the population biology of threatened/endangered plant species in the Midwest (including Viola conspersa, Platanthera leucophaea, and Lespedeza leptostachya). This research helped form the basis for long-term monitoring protocols on rare species in the Chicago region, in what is now the Garden's Plants of Concern program.
