My current research studies include molecular diagnostics (root pathogens, foliar pathogens, fungal endophytes, fungal decomposers) and evolutionary relationships among forest hosts and pathogens. My research also explores population genetics of forest hosts and pathogens, genetic relationships among forest hosts and pathogens in the northern hemisphere, the role of soil microflora in forest health, gene expression of forest pathogens causing disease, predicting potentially invasive pathogens, and influences of climate, disturbances, and other environmental factors on forest hosts, pathogens, and beneficial microbes.
My earlier research included molecular genetics of Populus spp., especially related to plant defense.
My research interests are numerous, but include forest pathology, molecular diagnostics of forest microbes, population genetics of forest hosts and pathogens, phylogenetics of forest pathogens, predicting invasive forest pathogens, predicting climate-change impact on forest disease, environmental influences on genetic structure of forest hosts and pathogens, woody plant defense systems, host/parasite interactions, expression of pathogen genes related to disease, the role of soil microbes in forest health, and woody plant endophytes and symbioses.
Forest pathogens (the cause of forest disease) and other beneficial forest microbes are key regulators of the growth, sustainability, productivity, and carbon sequestration of forests. Forest disease causes more long-term damage to forest productivity than any other natural disturbance, but this damage is frequently attributed to other factors. Furthermore, severe threats from invasive pathogens and diseases related to climate change continue to rise, and information is needed to address these threats. Precise DNA-based identification of forest pathogens and beneficial microbes is essential to determine their distribution, ecological role, and predictions of future behavior (including invasiveness), so that appropriate management practices can be developed and/or applied. Further understanding the genetic-based interactions of pathogens, host trees, and the abiotic and biotic environment is critical to managing forest diseases and maintaining healthy, sustainable, and resilient forests in a changing environment.
