    About Me


    B.S., Penn State University, 1980
    M.Ag., Penn State University, 1983

    Department Focus Areas:

    Integrated Pest Management
    Information Management and Knowledge Engineering


    Apiculture; control of parasitic mites; pollination


    Apiculture; public science education; international development work (have worked with African bees and beekeepers in Sudan, Uganda, Costa Rica, and Panama)


    The Insect Connection; Bug Camp for Teachers

    Extension Activities & Interests:

    I have responsibilities in the areas of apiculture extension, public science education and teaching. Current extension activities focus on a regional collaboration (MAAREC: The Mid-Atlantic Research and Extension Consortium) with researchers and other extension specialists in Delaware, Maryland, West Virginia and New Jersey. Our aim is to develop an IPM approach to control honey bee diseases and mites and to improve information transfer techniques through traditional and innovative methods. Current teaching responsibilities include team teaching a three credit undergraduate course "The Insect Connection" and a three credit course for Teachers "Bug Camp for Teachers." Current outrreach activities include the coordination of the following annual events: The Great Insect Fair, Bug Camp for Kids, Advanced Bug Camp for Kids and Bug Camp for Teachers.
