Research and Interests

My priority goals are the strategic expansion and effective management of the National Plant Germplasm System’s (NPGS) temperate forage legume collection of Medicago (alfalfa), perennial Trifolium (clover) and Lotus (trefoil), that consists of 16,000 accessions representing 380 species. Recent activities have focused on identifying and filling gaps in the taxonomic, ecogeographic, and genetic coverage of the collections, especially for crop wild relatives, relying heavily on geospatial analysis. Management efforts have focused on regeneration and seed monitoring using using best management gene banking practices. Our goal is the rapid distribution of vigorous, true-to-type seeds to researchers and breeders. As resources permit, I have been characterizing the collection with genetic markers and evaluating priority agronomic traits. Current research activities are focused on tracking from cradle to grave, transgene flow from genetically-engineered alfalfa to identify and mitigate routes of seed and pollen transmission to support coexistence among diverse alfalfa producers.
