Biography

L.J. Rotness joined the lab in 2008. As a researcher in the field of biomass, he draws on his experience in thermo chemical conversion, and GC analysis. His work is geared toward the operation, maintenance, and design of high pressure, high temperature continuous-flow systems. As an undergrad in the field of mechanical engineering, his educational pursuit combines scholastics with lab experience, handling and processing biomass and waste.
