Dr. Jansson leads development of a vision and strategy for PNNL and EMSL in plant sciences for bioenergy and environmental applications. These efforts include establishing partnerships, coordinate grant proposals, identifying capability gaps, and outlining where PNNL and EMSL can deliver enhanced impact to DOE and greater missions.

Director of Plant Sciences, EMSL, 2014-present. Leads development of a vision and strategy for PNNL and EMSL in plant systems biology and bioenergy. As Director of Plant Sciences,Jansson has established a growing and vibrant Plant Sciences Program. He has introduced the model grasses Brachypodium and Setaria as experimental plant systems, and they are now used in a large number of projects at PNNL, within and outside of EMSL. He also has introduced biomass sorghum as an EMSL focus in programmatic bioenergy research via grants from ARPA-E and BER. Jansson's research at PNNL encompasses plant biochemistry, plant-microbe interactions and genome-to-phenome mapping. He has initiated two strategic hires, Amir Ahkami in Molecular Plant Biology and Venkat Srinivasan in Multiscale Plant Modeling.

Senior Staff Scientist, Earth Sciences Division (ESD), Lawrence Berkeley National Laboratory (LBNL), Berkeley, 2008-2014; ESD Program Lead for Bioenergy 2011-2014. Research evolved around bioengineering of plants and cyanobacteria with emphasis on understanding and exploiting photosynthesis, lipid and carbohydrate metabolism and source-sink interactions. Lead-PI for two ARPA-E projects, "FOLIUM" aiming at using synthetic biology and metabolic engineering to establish tobacco as a platform for foliar production of advanced hydrocarbon biofuels, and "METHYLASE" with focus on using enzyme and metabolic engineering to design a novel enzyme and metabolic pathway for direct conversion of methane to liquid transportation fuels.

Professor/Chair, Mol. Biol., Dept. of Plant Biology & Forest Genetics, Swedish Univ. of Agricultural Sciences (SLU), Uppsala BioCenter, Uppsala, Sweden, 2000-2007; Head of Department, SLU, 2005-2007. Research centered on photosynthesis in cyanobacteria and metabolic engineering of starch biosynthesis in cereals.

Scientific positions of increasing recognition, from Assistant Professor to Full Professor, Department of Biochemistry and Biophysics, Stockholm University, 1987-1999. Research on photosynthesis in cyanobacteria and starch biotechnology in cereals.
