Tim Tschaplinski

Distinguished Scientist

ORNL


Research

Plant physiologist experienced in biochemistry, specifically the application of chromatographic analyses (GC-MS, HPLC) to research problems in genomics, bioenergy crop production, and environmental stress physiology. Current research includes metabolomics for phenotypic characterization of Populus and Arabidopsis, and the application of genomic tools for the accelerated domestication of Populus, including increasing the drought tolerance of Populus to increase biomass productivity, and manipulating secondary metabolite production for increased carbon sequestration potential.
