Principal Scientist

 

Current Research Interest

  • To unravel the dynamic complexity of plant disease resistance mechanism and cross-talk of GSH with other established signaling molecules to combat environmental stress`s in planta;
  • To elucidate biosynthetic pathways of plant secondary metabolites viz. podophyllotoxin;
  • Plant Metabolic Engineering: Genetic manipulation of plant natural products that have a potentially beneficial biological effect.
