My specific research skills and interests are oriented to using field-based research to reduce the impact of weeds on cropping system productivity.  I seek integrated approaches to weed management using chemical, cultural, biological/cultural, and physical manipulations of the cropping system.  I often use laboratory and greenhouse research in support of my field program in order to explore the fundamental questions that arise during the research process.

As a specialist, I often conduct collaborative research with farm advisors, faculty, and other specialists in order to effectively and efficiently serve the statewide perennial crop industries.

Currently, my lab has three primary research focus areas:

  1. chemical and cultural weed control research in newly planted and established perennial crops, and support for weed control in annual cropping systems;
  2. basic and applied research on the development, management, and physiology of herbicide-resistant weeds;
  3. soil fumigation research related to soilborne pest control performance in perennial crop nurseries and orchard replanting, and supporting the emissions reduction research of our USDA-ARS collaborators.
