Plants and pathogens have been battling each other for millennia, but we still know little about what determines the outcome of these encounters. My research interests have been focused on plant-pathogen interactions especially chemical defenses in the woody host against fungal infections, phytohormone signaling, and regulation of such defense reactions. I use a range of biochemical and molecular techniques to understand the defense mechanism of the woody host Another important aspect of my research is to understand more about the interaction between poplar and its fungal pathogens to determine other, molecular strategies used by the tree in its defense and investigate how the pathogen can evade the tree defense.
