Biography

Dr. Pubudu Handakumbura is a Staff Scientist and a Team Lead in the Environmental Transformations and Interactions group at EMSL. She is using systems and synthetic biology approaches to study plant-microbe-soil interactions. The main focus areas of her current research are to develop biomarkers to engineer and improve crop resilience under changing climates, to improve photosynthetic performance and carbon partition in plants and enhancing feed stock attributes in lignocellulosic biomass for bioenergy production. Dr. Handakumbura has extensive experience in advanced molecular biology techniques and genetic engineering, plant tissue culture and plant multi-omics techniques. She leads the Molecular Plant Phenotyping efforts at EMSL.
