Bruno Klein is a research engineer in the Economic Sustainability & Market Analysis group. His focus is on techno-economic analysis (TEA) and life cycle assessment (LCA) for biomass conversion pathways to biofuels and bioproducts. Prior to joining NREL in 2019, Bruno worked for six years at a Brazilian national laboratory with the assessment of biomass conversion through various technologies.
