Professional Responsibilities and Activities

  • Administration:
    Responsible for directing and managing the Doctor of Plant Health Program offered at the University of Nebraska–Lincoln. The mission of the Doctor of Plant Health Program (https://dph.unl.edu/) at UNL is to produce plant practitioners who are broadly trained in the various disciplines that impact plant health and plant management. These practitioners will be capable of integrating this broad training to diagnose and solve plant health problems and to develop plant management systems that maximize the system's economic, environmental and social sustainability
  • Research:
    Responsible for IPM and arthropod applied ecology in dryland crops and agroecosystems. Current research focuses on understanding and solving pest management challenges in cereal crops and sunflower.
  • Teaching:
    Instructor for Pest Management Systems.
  • Major Project Activities:
    - Evaluating the role of soil arthropods in soil health
    - Development of IPM strategies in sunflower
    - Developing a team-based approach to wheat stem sawfly solutions in wheat
