Positions
- Extension Associate Sr, Plant Pathology and Plant-Microbe Biology (PPPMB), College of Agriculture and Life Sciences (CALS)
I have been the Director of the Plant Disease Diagnostic Clinic of the Department of Plant Pathology at Cornell University since July of 1998 and the Associate Director of the Northeast Plant Diagnostic Network since November of 2002. I was born to diary farming and grew up in New Jersey. I received my Bachelor of Science degree from Cornell in Floriculture and Ornamental Horticulture. I became very interested in plant pathogens during my undergraduate work and decided to pursue a Masters of Professional Studies degree in the department of Plant Pathology. My Masters research focused on an evaluation of onion flower susceptibility to a known fungal pathogen. As Director of the Clinic, I am responsible for diagnosing plant diseases on a wide range of host plants such as woody ornamentals, herbaceous plants, fruits, vegetables, turfgrass, and field crops. Additional duties include training Master Gardeners, Extension Educators, and other green industry members on the basics of plant disease and the pathogens that cause them, as well as introducing youth to the vast world of fungi. As Assistant Director of the NEPDN, I support the overall mission of providing detection of a possible bioterrorist attack of the nationÕs natural and agriculture systems.

Teaching
teaching overview
- Karen's teaching focuses on basic plant pathology and diagnosing plant problems. She often gives guest lectures about basic plant pathology, diagnostic clinics, the National Plant Diagnostic Network (NPDN) and the importance of early detection of high consequence pathogens and pests in courses such in Entomology, Plant Pathology and Horticulture
Service
outreach overview
- As Associate Director of the Northeast Regional Center, a component of the National Plant Disease Network (NPDN), my duties include maintaining a regional center capable of supporting the diagnostic needs of 12 northeastern states. My duties also include close interaction with land grant university diagnosticians, software engineers, university department chairs, and state and national regulatory personnel. I represent all NPDN member diagnosticians on the National NPDN operations committee. As Program Area Manager of the diagnostics committee, I provide leadership in the creation of Standard Operating Procedures, coordination of highly sophisticated, identification procedure training events, and maintaining active communications of significant events. As Program Area Manager of the national database committee, I provide leadership in the creation of Upload Guidelines for those submitting diagnostic identifications to the National Repository at Purdue University and in reviewing the host and pathogen EPA pest codes for appropriate content and accuracy. My extension teaching programs are geared toward audiences that include Master Gardeners, Extension Educators, other green industry members, and students. They focus on basic plant pathology, plant disease diagnostics, and the operation of the NEPDN. I am responsible for overseeing the diagnosis of plant diseases on a wide range of host plants such as woody ornamentals, herbaceous plants, fruits, vegetables, turfgrasses, and field crops, as well as conducting large scale surveys searching for harmful, introduced pathogens of high concern and those pathogens that are capable of causing significant damage to agricultural or natural environments and may be intentionally or unintentionally introduced.
