Jonas Sjöblom

Associate Professor at Energy Conversion and Propulsion Systems

My research is broadly about emissions from transportation. Subtopics include heterogeneous catalysis, reactor modelling, catalytic aftertreatment systems in connection to internal combustion engines, particulate emissions, aerosol characteristics and transformation, real driving emissions and emissions monitoring. The objective is to bridge these research areas to enable more environmental friendly transport systems combined with zero climate impact.

Some of the tools used are Design of Experiments (DoE), Multivariate data analysis (MVA) and Parameter estimation methods. The research is performed in collaboration with many other disciplines including chemistry and medical research.
