Ryan’s Research and Interests: I help to manage the MN Tree Inspector Program, a collaboration with the MN Department of Natural Resources. I also assist with research focusing on improving clonal propagation in elm as part of the U of M Elm Selection Program. A third aspect of my research is focusing on the utilization of urban grown ginkgo seeds for food and medicine. Our hope for the ginkgo project is to create a mechanism for harvesting and selling urban grown ginkgo seeds to alleviate concerns over the malodorous seeds, which often result in requests for these quality urban trees to be removed.
