Dr. Eaton engages in cross-cutting research to improve the efficiency and reduce emissions within our energy and transportation systems. His focus areas include alternative fuels processing, high efficiency clean combustion and exhaust aftertreatment catalysis. He obtained his Ph.D. in Chemical Engineering in 2015 from the University of Maine where he helped develop the Thermal DeOxygenation process; a thermochemical conversion technology to transform cellulosic biomass into biofuels. He made discoveries in the decomposition of biomass-derived levulinate and formate salts which led to critical engineering design improvements and process scalability.  Prior to joining USM, Dr. Eaton has served as Assistant Research Professor of Chemical Engineering at the University of Maine as well as Assistant Professor of Engineering at Maine Maritime Academy where he also served as Assistant to the Director of the Marine Engine Testing and Emissions Laboratory; a Tier I Department of Transportation Research center.   

Dr. Eaton also has research and technology development experience within the private and government sectors.  He completed a Post-Master’s research associateship at the Oak Ridge National Laboratory’s Fuels, Engines and Emissions Research Center where he made contributions to Homogeneous Charge Compression Ignition (HCCI) engine development as well as in the speciation and fate of exhaust impurities (such as metals and phosphorus) in catalytic exhaust systems.  He currently serves as the Chief Technology Officer for two Maine-based start-up alternative fuels companies.

Dr. Eaton has authored 18 peer reviewed scientific journal articles and has been awarded five patents for alternative fuels technologies.  He currently sits on the ASTM D37 standards committee and on the Transportation Research Board’s Standing Committee on Marine Environment (AW030).  He has received a diversity of funding including from the National Science Foundation, the Department of Energy, Maine Technology Institute and the Department of Transportation.  

Research Interests

Dr. Eaton’s current research interests include multiphasic fuel injection dynamics, low temperature heterogeneous catalysis for emissions reductions and alternative fuels processing technologies.
