Biography

Todd Hart has more than 20 years experience in the research field. His work has mainly been directed toward developing a diverse technical expertise in analytical equipment and process controls. Mr. Hart has developed many unique methods for IC, GC, GC/MS/IR, ICP-OES, TGA/IR and TGA/MS analysis of samples ranging from bio-agriculture chemicals to Hanford tank wastes. His experience includes handling and processing, biomass, and wastes primarily in high-pressure batch and continuous-flow processing reactor systems and their design. This research has also involved an extensive study of catalysis systems. Mr. Hart has been named on two patents, and on the 1999 Presidential Green Chemistry Challenge Award, Economic Conservation of Cellulosic Biomass to Chemicals.
