Research plant pathologist, Jenny Juzwik, conducts studies on diseases of trees that impact forest health and productivity.
Her career-long interest and passion has been the study of interactions among microorganisms and insects associated with disease occurrence and development. One particular focus has been on the insects responsible for transmission of the oak wilt fungus, Bretziella fagacearum. In 2014 she completed research that involved elucidation of the major biotic determinants of hickory decline and investigation of the role(s) putative pathogens play in the complex. In 2010, she initiated 13 years of investigations 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, as well as other pathogenic fungi that may cause symptoms similar to those of thousand cankers disease.
