I am studying two new ascomycete pathogens (Genus Ceratocystis), which are associated with Rapid Ohia Death (ROD) on the Big Island of Hawai’i. ROD has decimated large stands of Ohia lehua trees (Metrosideros polymorpha), which are endemic to the Hawai’ian islands and are important for local ecosystems. Moreover, Ohia trees are a vital part of Hawai’ian culture. My work focuses on patterns of fungal colonization and tree host responses associated with ROD.
