Naganand Rayapuram

Research Scientist

Research Group: Heribert Hirt

Research Interests

​Currently his interests revolve around finding novel substrates of MAP Kinases involved in biotic stresses in Arabidopsis thaliana that regulate gene expression using a large scale phosphoproteomics approach. The long-term objective is to use a combination of reverse genetics, molecular biology and biochemistry to efficiently assign the substrates to their bonafide kinases.
