Biography and Education

Biography

I grew up in Wisconsin and developed a life-long interest in plants while exploring the state parks and forests. I earned a B.S. in Botany from UW-Madison, where I gained research experience studying fungal diseases of cranberries.  I earned a Ph.D. in Plant Pathology from Cornell University. My dissertation work focused on the epidemiology and management of grapevine downy mildew, including 3 field seasons working in South Australia. I studied fire blight, an important and potentially devastating bacterial disease of apples, at Michigan State, as a postdoctoral research associate. I started my position at KSU in 2006. My program includes research, extension, and diagnostics for horticultural commodities (turfgrasses, trees, ornamentals, fruits, and vegetables.) I have mentored several undergraduate and graduate students. In addition to my research and extension roles, I am active in the American Phytopathological Society (APS) and currently serve as a Senior Editor for the APS journal Plant Disease and am a member of the Board of the APS Office of International Programs (OIP).

Education

Ph.D. Plant Pathology, Cornell University, 2005
B.S. Botany, University of Wisconsin-Madison, 1999

Staff and Students

Mingying Xiang - PhD Student (co-advised, Horticulture)

Research

My research covers many horticultural commodities, with a focus on integrated disease management. My students have conducted and published work on large patch of zoysiagrass (caused by the fungus Rhizoctonia solani), dollar spot in turfgrass (caused by the fungus Sclerotinia homoeocarpa), and the weedy species silvery thread moss (Bryum argenteum). I have also participated and mentored undergraduate and graduate students involved in research on tomato grafting, tomato microbial communities, pine wilt disease, organic pac choi production, and other systems.

Extension

My extension program covers a wide array of horticultural commodities, including turfgrass, ornamentals, trees, fruits, and vegetables. I work with diverse audiences in diverse settings. I develop and deliver education programming through traditional face-to-face presentations, hands-on workshops, print publications, and various online delivery systems. I also handle disease diagnostics for commercial horticulture crops that are submitted to our Plant Disease Diagnostic lab.

 

One key piece of my extension program delivery is the K-State Turf and Landscape blog:

Teaching

I do not have a formal teaching appointment. However, I give several guest lectures each year in undergraduate courses in Plant Pathology and Horticulture. In addition, I co-teach a summer field course for graduate students and mentor graduate students who conduct formal internships in the diagnostic laboratory.
