Senior Research Associate
Research on such classical diseases as apple scab and grape powdery mildew has been continuous and intensive throughout the last century. However, relatively few investigations have had a major impact upon how we approach controlling those diseases. An overall goal of my research has been to identify those areas of pathogen biology, ecology, and epidemiology that are poorly understood, and which severely constrain our ability to improve disease management programs. The research frequently spans disciplinary, institutional, and international boundaries, and has involved collaborations with horticulturists, food scientists, and entomologists from the other departments at Geneva, and in countries from Norway to Australia.
I am particularly interested in how plant pathogens survive the intercrop period to restart epidemics after a period of overwintering and dormancy. This is an under-researched area and one in which I can make meaningful contributions.
Outreach and Extension Focus
It`s a 2-way street. I use my contact with stakeholders to refine research directions and ideas; to keep them useful and relevant to the industry. It`s also an opportunity to educate the stakeholders in my research findings and their practical application.
I do not have many opportunities to teach, but I take advantage of those that arise. Being the faculty member at Geneva with experience in turf pathology, I lead the Field Plant Pathology course section on turf diseases. I also arrange demonstrations and brief lectures for elementary and middle school students during visits to the Experiment Station. These generally occur 2-3 times per year.
More recently, in 2006 I began to teach a series of 6 lectures on preparing competitive grant proposals (at Cornell and at Univ. Norway) and writing articles for refereed journals (Univ. Norway).
In 2011 I will be teaching a short course at the Univ. Norway on Ontogenic resistance and plant disease.
This year I am coordinating PLP 660, a graduate independent study course focusing on imaging and graphics for research and extension publications and presentations.
