Education

  • Ph.D. – Weed Science – North Carolina State University
  • M.S. – Weed Science – Michigan State University
  • B.A. – Political Science – Hope College, Holland, MI

Extension

  • My extension program focuses on developing and disseminating weed control recommendations and other technical information appropriate to agronomic and commercial vegetable crops.  Technical information emphasizes weed biology and ecology.  Extension responsibilities include assisting with weed management for agronomic crops in New Jersey.

Research

  • Research efforts fall into five main areas: weed biology and ecology, integrated pest management, cover crops for weed management, herbicide-resistant weeds, and herbicide evaluation.  Research has focused on agronomic and commercial vegetable crops important to the mid-Atlantic region.
