I have 31 years of experience, and specialize in the field of agricultural engineering with specific knowledge in the areas of grain drying, grain storage and vegetable storage. I have published on such topics as grain aeration, grain drying and potato storage. I have testified 10 times on topics such as potato storage, grain storage and grain storage quantity. As an extension engineer I provide education and technical assistance to business and farmers. An extension engineer position is a cross between consulting engineer and educator.
