Research Scientist in Functional Genomics of Cereals


I am a plant molecular biologist with activities in identification of novel stripe rust resistance genes, in modification of a known defeated stripe rust resistance genes to engineer its functionality against novel isolates of stripe rust, in measuring wheat transcripts when modifying circadian clock genes in wheat toward improving its response to abiotic stresses under a climate change reality and in pyramiding a collection of different disease resistance genes in elite winter wheat germplasm using marker assisted selection.

Current research and/or projects

I use molecular genetic techniques to study plant response to fungal pathogens and to to environment, plant development and organization of plant fungal pathogens toward protecting yield of cereal crops.
