Current Research
My current research studies focus on the phylogeography of forest pathogens. I am involved with developing molecular methods to characterize and identify forest pathogens and endophytes. My research also includes studying the effects of climate change on the pathology and distribution of forest pathogens and their hosts.
Research Interest
My research interests reside in forest pathology.

Year: 2022New research provides promising insights toward developing novel approaches to manage this devastating forest disease. -
Year: 2020At least three different biotypes (genetic groups) of the invasive myrtle rust pathogen (Austropuccinia psidii) were identified, each with different host associations, geographic distributions, and potential distribution (suitable climate space). Each biotype poses its own distinct invasive threats to diverse hosts in the Myrtaceae (e.g., eucalypts, guava, ‘ōhi’a) grown in different geographic areas. -
Year: 2017Species of the fungal genus Armillaria are associated with forest ecosystems worldwide. Some species are destructive root disease pathogens, while others are beneficial decomposers. Correct species identification is essential when assessing their threats. RMRS scientists are using DNA-based tools to correctly identify Armillaria species, which helps identify where invasive pathogen risks may occur.
