Stephanie L. Greene is a Supervisory Plant Physiologist at the USDA Agricultural Research Service National Laboratory for Genetic Resource Preservation and affiliate faculty member with the Soil and Crop Science Department at Colorado State University, Fort Collins, Colorado. She holds a PhD in Plant Breeding from Kansas State University, Manhattan, Kansas.  Her responsibilities with the US National Plant Germplasm System started 26 years ago, working as a vegetable and forage gene bank operations manager in Geneva, New York, then as the USDA temperate forage legume curator in Prosser, Washington, and now as seed curator for the NPGS security back up seed collections. Her research interest is the ex situ conservation of plant genetic resources, especially crop wild relatives native to North America.

Karen A. Williams is a Botanist with the USDA Agricultural Research Service National Germplasm Resources Laboratory in Beltsville, Maryland. She has an MS in Soil Science from the University of Florida, Gainesville, Florida.  She manages the Plant Exploration Program for the US National Plant Germplasm System and has overseen the adaptation of the Program to the changing international regime on access and benefit sharing over the past 20 years. She has been involved in the collection, conservation and documentation of crop wild relatives in several countries.  One of her current interests is the development of partnerships among different institutions to link in situ and ex situ conservation of crop wild relatives in the United States.
