Research interest:

My research focus is on receptor kinase FERONIA-mediated signaling in Arabidopsis thaliana. FERONIA is involved in many aspects of a plant’s life, such as reproduction, root development, vegetative growth and responses to abiotic and biotic stresses. We are using genetic, genomic, proteomic, molecular and biochemical approaches and network construction to try to understand the molecular mechanisms through which FERONIA receptor kinase regulates plant growth and stress in response to different environmental conditions.
