Daniel Miki Santosa is a chemical engineer from the University of Washington and has a broad research background and skillset. His career started with the development of an operational prototype separation system for capturing stranded landfill gases in a start-up natural gas company. Before that, he has a broad research experience at the University of Washington in both clinical research and bioengineering as an undergraduate student. His expertise includes process development of laboratory and engineering prototypes, reactor scale up, reaction engineering, techno-economic analysis and project management. Currently, he is the capability manager for bench-scale pyrolysis and hydrotreating systems for upgrading of biomass to fuels and chemicals at the group.
