Charlotte R. Hewins





Research Specialist


B.S. 1993, Lake Erie College


Research Interests


I have been a member of the research department at The Holden Arboretum since 1992, providing support for the plant breeding and genetics program, including field and lab work, such as making cross pollinations, collecting plants and doing germination experiments, micropropagation and molecular characterizations. Currently, I have been supporting the soil ecology research group and addressing questions concerning the interactions between plants and soil microorganisms. This work includes soil enzyme analysis, carbon and nitrogen analysis and DNA-based analysis of soil microbes and especially soil fungi. I also provide general technical assistance, field, and lab support to our staff of research scientists and oversee lab management.
