Graduate Student Researcher

Bio

Emilio is a PhD Candidate in Energy Science and Engineering in the Bredesen Center, a joint program between the University of Tennessee, Knoxville and Oak Ridge National Lab. He earned his bachelor’s in Mathematics from University of California, Santa Barbara. Prior to joining the Bredesen Center he operated and maintained an industrial 24 MWe biomass combustion fluidized bed, where he created empirical models to optimize and increase plant reliability. He also interned at the National Renewable Energy Laboratory, where he developed a pilot scale biomass gasification catalytic reactor model using ANSYS Fluent. Currently he is using MFIX, an open source Fortran CFD code, to improve mixing, heat transfer, and chemistry in fluidized bed biomass fast pyrolysis reactors. He works with experimentalists at the National Renewable Energy Laboratory and the National Energy Technology Laboratory to validate fluidized bed simulations. He is a member of the Consortium for Computational Physics and Chemistry, a multi-laboratory, multi-scale, computational modeling collaboration to improve bio-oil quality, upgrading catalyst, process integration, and scale-up (http://cpcbiomass.org/).
