My laboratory is interested in the interaction between plants and insects. In particular, we study how plants respond to insect attacks, and the mechanisms used by insects to avoid plant defenses and to take over plant metabolism. We are also interested in the role of secreted ribonucleases in these defense interactions.

Our current projects are:
- Characterization of the transcriptional and metabolic changes induced in soybean by the soybean aphid, Aphis glycines.
- Role of general stress responses in the interaction between plants and aphids.
- Identification of novel signaling pathways that control defense responses to insects and mechanical wounding in Arabidopsis and soybean.
- Biological roles of secreted ribonucleases in defense responses and also in other cellular processes.
