 Profile

I am a native of the mountains of eastern Tennessee. I have a B.S. in Agriculture – Plant and Soil Science, and M.S. in Plant and Soil Science from the University of Tennessee. My thesis project focused on woody tree and shrub liner production. I have worked as an herbaceous perennial grower for Zelenka Nurseries, a production manager for Brussel's Bonsai Nursery, a bedding plant grower for Van Wingerden International, and an Integrated Pest Management(IPM)coordinator for Costa Farms - Costa Carolina.

 Research Interests

My primary interests are in Integrated Pest Management (IPM), herbaceous perennial production and cultivation, annual and bedding plant production and cultivation, woody ornamental (tree and shrub) production and cultivation, plant growth regulator techniques and combinations, and minimizing ornamental production and cultivation impacts to water and other natural resources.
