Positions
- Associate Professor, Plant Pathology at Geneva
My program specializes in applied plant pathology, mycology, and community/stakeholder education. The programÕs mission is to provide a better understanding of the relationships between life history features of fungal plant pathogens of fruit crops and applied disease management practices. Understanding the impacts that management practices have on aspects of pathogen life history such as survival, inoculum production, community structure, and propensity for resistance development will, in turn, allow for the sustainability and refinement of such practices to better manage disease.

research overview
- My research program focuses on integrating basic and applied research to develop improved management strategies for fruit diseases of concern to New York producers. In recent years, basic research endeavors in the form of plant biotechnology have made considerable contributions to the management of fruit diseases. However, efforts are still needed to improve the concepts and products of basic research so they may be more readily applied to solve disease problems. Hence, although much of my research is concerned with applied aspects of fruit diseases, a portion of my research program will be dedicated to conducting basic research in the hope of developing products with potentially broad or far-reaching applications. Currently, my appointment is 50% extension and 50% research. Because of this split, I endeavor to interweave my research program goals with those of my extension program such that my research endeavors lead to stakeholder-relevant extension deliverables. In turn, I allow stakeholder needs and extension concerns to guide my research efforts. Therefore, both my research and extension efforts focus on similar disease problems in NY and lead to related accomplishments. To address both applied and basic research philosophies, and both research and extension aspects of my appointment, I have established the following goals: 1) Investigate the biology and management of fungal diseases of apple, stone fruit, and small fruit using cultural, biorational, and organic approaches; 2) Understand the biology and management of site-specific fungicide resistance and antibiotic resistance in pathogen populations responsible for apple scab and brown rot of stone fruit; 3) Develop gene expression technology for improving the application of transgenic crops. My specific research objectives are to: 1) Understand cryptic infections of bud wood by the fire blight pathogen Erwinia amylovora and the prevalence and mechanisms of antibiotic resistance in E. amylovora populations; 2) Manage diseases of apples, stone fruit, and bush berries using cultural, organic, and biorational approaches; 3) Understand the prevalence, mechanisms, and potential to manage practical resistance in populations of Monilinia spp., the causal agents of brown rot, shoot blight, and blossom blight of stone fruit; 4) Investigate the persistence, prevalence, mechanisms, and factors resulting in the development and selection for practical resistance in populations of Venturia inaequalis, the causal agent of apple scab.

outreach overview
- My extension program is concerned with producer and stakeholder disease and pesticide education and with the identification and management of emerging disease problems of tree fruit and berry crops in New York. The specific objectives of my program are to: 1) maximize use of web-based technologies in extension education and to deliver season-specific information on emerging disease concerns and management strategies; 2) use molecular tools to identify emerging disease problems and disease management concerns for the development and sustainability of the NY fruit industry; 3) educate the stakeholder and consumer community on organic and conventional disease management practices to promote product sustainability and environmental stewardship.
