Current Research Focus

My research focuses on understanding plant defense responses induced by one of its signaling compounds, extracellular ATP (exATP). I am using Arabidopsis plants and different classes of pathogens such as fungi, oomycetes, bacteria and viruses to assess extracellular ATP-induced defense responses. I am also interested in unraveling the molecular mechanism of extracellular ATP-mediated signal mechanism in plants.
