Research Interest

Plants have a variety of defense responses to protect themselves against insect pests and pathogens. These include the production of chemicals, from small organics to large proteins and enzymes. My research interest is to understand plants defense mechanism, the associated signal transduction pathways and activation of component resistance genes. Aim is to augment the resistance of crop plants against insect-pests and pathogens
