Areas of Interest: 

Molecular plant pathology

Current Research: 

Plant pathogens are ever-evolving challenges to the production and quality of crops. Genetic resistance to pathogens is the most crucial strategy to overcome this challenge. Research in my Lab focuses on 1. Investigating how the plants interact with their pathogens and 2. Developing solutions to fungal diseases of small grain crops including wheat and barley.  Using Fusarium graminearum, the causal organism of Fusarium Head Blight in wheat and barley, as a model we are investigating the broad-spectrum strategies that the plants use to resist the pathogen spread. Another research area of interest to the Lab is exploring and applying genetic solutions to the diseases of wheat and barley.  The long term applications of the work involve applying the findings towards solving diseases in other crops caused by Fusarium spp.
