Sievers’ research interests are in heterogeneous catalysis, reactor design, applied spectroscopy, and characterization and synthesis of solid materials. Combining these interests he seeks to develop processes for the production of fuels and chemicals. His research program combines fundamental and applied research.

In fundamental studies, a suite of analytical and spectroscopic techniques (e.g. IR, NMR) is used to gain knowledge on structure-reactivity relationships of heterogeneous catalysts. Moreover, surface reactions are studied on a molecular level to identify reaction pathways over different catalysts. Information obtained from these studies provides the foundation for designing innovative catalysts.

Applied studies focus specific catalytic processes. For these projects, continuously operated flow reactor systems are designed. Different catalysts are tested for reactivity, selectivity and stability and the influence of the operating conditions is investigated. Catalyst deactivation is studied in detail to develop suitable regeneration methods or to avoid deactivation entirely by improved catalyst design. Specific projects include hydrodeoxygenation of pyrolysis oils, selective hydration of polyols, conversion of sugars into lactic acid and ethylene glycol, and selective oxidation of methane.

An important goal of Sievers’ research is to enable technology for utilization of alternative resources in order to reduce the current dependence of oil. Among these biomass is a particularly promising candidate because it is renewable and can be produced CO2 neutral.

Sievers has contributed to 80 peer reviewed publications on heterogeneous catalysis in petroleum refining (isobutane/2-butene alkylation, fluid catalytic cracking, hydrotreating), alkane activation, supported ionic liquid as catalysts for fine chemical synthesis, and biomass processing.  He is Director and Past President of the Southeastern Catalysis Society, former Program Chair and Director of the ACS Division of Catalysis Technology & Engineering, former Director of the AIChE Division of Catalysis and Reaction Engineering, and Editor of Applied Catalysis A: General.

    Dr. Realff’s broad research interests are in the areas of process design, simulation, and scheduling. His current research is focused on the design and operation of processes that minimize waste production by recovery of useful products from waste streams, and the design of processes based on biomass inputs. In particular, he is interested in carbon capture processes both from flue gas and dilute capture from air as well as the analysis and design of processes that use biomass.

    Associate Professor, Woodruff School of Mechanical Engineering
    Woodruff Faculty Fellow
    IMat Initiative Lead | Materials for Energy Storage
    SEI Lead: Energy Storage

    Matthew McDowell joined Georgia Tech in the fall of 2015 as an assistant professor with a joint appointment in the George W. Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering. Prior to this appointment, he was a postdoctoral scholar in the Division of Chemistry and Chemical Engineering at the California Institute of Technology. McDowell received his Ph.D. in 2013 from the Department of Materials Science and Engineering at Stanford University.

    McDowell’s research group focuses on understanding how materials for energy and electronic devices change and transform during operation, and how these transformations impact properties. The group uses in situ experimental techniques to probe materials transformations under realistic conditions. The fundamental scientific advances made by the group guide the engineering of materials for breakthrough new devices. Current projects in the group are focused on i) electrode materials for alkali ion batteries, ii) materials for solid-state batteries, iii) interfaces in chalcogenide materials for electronics and catalysis, and iv) new methods for creating nanostructured metals.

    SEI Lead: Energy & Manufacturing

    Tequila A. L. Harris is a Professor in the George W. Woodruff School of Mechanical Engineering, and is the director of the Polymer Thin Film Processing Laboratory (tharris@gatech.edu). Her research focuses on investigating the fundamental science associated with manufacture of polymer thin films from fluids (e.g., solutions, dispersions, slurries, etc.) as they are coated onto permeable or impermeable surfaces to make components or devices. She explores the connectivity between thin film functionality, based on their manufacture or structure, and their life expectancy, to elucidate mechanisms by which performance or durability can be predicted. In addition to conducting computational analysis, developing analytical models and running experiments, Harris also develops new manufacturing technologies to fabricate thin films, in wide area or discrete patterns. Target applications are well-suited for a variety of industries including food, energy, electronic, and environmental systems to name a few. In conjunction with her research activities, she is committed to the education, mentoring, and advisement of students towards scholarly achievements. She has published over fifty peer-reviewed articles. Harris has several awards including the National Science Foundation's young investigator CAREER Award and the Lockheed Inspirational Young Faculty Award.
