GOALS FOR NEXT 5 YEARS:

    Develop a research theme (Hatch Project), focusing on forage plant species, inter- and intra-specific interactions and influences of the environment
    Pursue scientific and applied research of relevance to Ohio, USA, and world forage agriculture, and especially to promote applications for use of forage species under grazing
    Develop undergraduate/graduate teaching/advising to support the above two goals
    Develop interactions with the Ohio, USA and international forage industry to ensure that my research and teaching are both relevant to current problems and are extended to others
