Professional activities / interests
My current research interests lie primarily in the area of identification, molecular characterization and breeding of genes/QTL that make wheat plants more resilient against different biotic and abiotic stresses. In particular, I am focusing on breeding and unscrambling of the genetic and molecular basis of resistance and other mechanisms against various devastating diseases (i.e. fusarium head blight, loose smut, common bunt and cereal rusts) and insects (i.e. wheat stem sawfly and orange wheat blossom midge), pre-harvest sprouting, end quality traits, drought tolerance, better agronomics and high grain yield.
