My research (carried out in collaboration with numerous scientists at the Garden, including Drs. Jeremie Fant and Kayri Havens) uses the tools of ecological genetics to answer questions aimed at making ecological restoration practices as economically feasible and successful as possible. Most of my work takes place in the western United States, where there is a great need for restoration on a large-scale. Restoration efforts are often hampered by a lack of information about which species and seed sources should be used to achieve desired restoration outcomes. Even when this information is known, the availability of seeds often limits what can be done for the restoration. I use ecological genetics research to inform the selection of species and seed sources for restoration, and to support the development of native plant material that will allow species diversity and ecosystem function to be restored to degraded arid environments in the western U.S.

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.
