Kamaranga (Shantha) Peiris 


Shantha is a Post Doctoral Researcher working on NIR and FTIR spectrometric/microscopic methods for evaluation of single kernels of wheat and for studying various traits of insects. Current research projects focus on developing methods for identification of Fusarium damage and estimation of deoxynivalenol levels in single kernels for fusarium head blight resistance evaluation of wheat and for age grading and species identification of insect vectors.
