Clare Casteel
Associate Professor, School of Integrative Plant Science, Plant Pathology and Plant-Microbe Biology Section
Interests
Plant-virus-vector and plant-insect interactions
Molecular & chemical ecology and soil microbiomes
Healthy agroecosystems, climate resilience and organic farming
Recent Research
The primary research goal of the Casteel lab is to identify the functions of microbes in plant-insect interactions and elucidate the key molecular mechanisms responsible for these relationships. The lab’s current focus is on pathogenic microbes and understanding how they counter plant defense in complex communities with insects and on understanding how beneficial microbes and microbiomes can be leveraged to mitigate the negative impacts of climate change through healthy agroecosystems and microbe engineering.
Outreach and Extension Focus
Viruses, aphids, diversified vegetables, organic agriculture, climate resilience, vector-borne plant pathogens
