My research focuses on the identification and characterization of genes and signal transduction pathways involved in plant immunity against microbial pathogens, particularly the roles and molecular mechanism by which the ubiquitination system regulates host defense responses in plants. Given that plant immunity is inextricably connected to plant development and environmental factors, my research also involves understanding the signaling crosstalk that orchestrates plant responses to different intrinsic and extrinsic signals. The long-term goal of our research is to elucidate and eventually manipulate for crop improvement the key molecular mechanisms that plants use to defend themselves against different biotic and abiotic stresses. To this end, a combination of cellular, molecular, biochemical, genetic, genomic and proteomic approaches will be employed to address relevant questions.
