PNNL

Davidson started with PNNL January 2016 as a Post Doc researcher. His research interests are in the area of heterogeneous catalysis and chemical process development. His research activities include the steam reforming of bio-derived compounds, both model compounds and aqueous phase bio-oil, for the production of hydrogen and utilization of these same feedstocks for the production of olefins. His current work is focused on both ammonia production and process intensification of ethylene production from ethanol.
