Forest Pathology

As a Research Plant Pathologist with the U.S. Forest Service, I conduct studies on diseases of trees that impact forest health and productivity. These studies often are conducted in collaboration with scientists, forest health specialists, and foresters in federal, state and county agencies as well as universities.

My career-long interest and passion have been the study of interactions among microorganisms and insects associated with disease occurrence and development. One particular focus has been on those insects responsible for transmission of the oak wilt fungus,Ceratocystis fagacearum. My ongoing research involves elucidation of the major biotic determinants of hickory decline and investigation of the role(s) putative pathogens play in the complex. In 2010, I initiated a preliminary investigation of bark and ambrosia beetles associated with eastern black walnut in the Midwestern states and their potential as carriers of the Thousand Cankers Disease fungus,Geosmithia morbida.

A major goal of my research is to provide practical disease management guidelines that address preventing establishment of invasive pathogens, detecting or monitoring activities, or control/ mitigation efforts.
