David Robert Emberson

About

I have been a post doctor and researcher here at NTNU since 2015, working in the Department of Energy and Process Technology. I have recently moved to the Department for Marine Technology as a førsteamanuenisis (Associate Professor). My specialism is combustion in the internal combustion engine, and I have been working in this field since since 2012. I have particular interest in direct injection compression ignition and spray characterization and have worked on a number of experimental developments. I have recently become interested in the switch to ammonia as a primary fuel in engines, and the devilment of the new technologies and techniques this switch will require.
