MSE Profile

Emma Hu joins the School of Materials Science and Engineering at Georgia Tech as an assistant professor. Her group will use quantum mechanical modelling combined with materials informatics to understand the underlying mechanisms of energy harvesting and utilization at the atomic level, and reveal structure-property-performance relationships for knowledge/data-driven materials design.

Her research seeks to accelerate the discovery of materials with complex properties to solve time-sensitive problems involving green energy production and climate remediation.

Emma obtained her Ph.D. in Physical Chemistry in 2018 from the University of California, Riverside, and her B.S. in Chemistry in 2013 from University of Science and Technology of China. She then spent two years as a postdoctoral scholar in the Center for Nanophase Materials Sciences at Oak Ridge National Laboratory from 2018-2020. Before joining Georgia Tech, Emma was an Assistant Professor at City University of New York from 2020-2023.

ChBE Profile Page

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.

Our group is primarily a surface chemistry and physics group which focuses on the use of high-powered pulsed lasers, low-energy electron scattering, micro-plasmas, mass spectrometry and ultrahigh vacuum surface science techniques. We use this "tool-set" as well as some scattering theory to unravel the details of non-thermal processes occurring under a variety of non-equilibrium conditions. Our group is based upon an interdisciplinary approach and thus our research programs span the realm of fundamental investigations in molecular physics, surface physics and chemistry, bio-physics, bio-polymer formation under pre-biotic conditions as well as working in applied areas of relevance to analytical technique developments, atmospheric chemistry, catalysis and molecular hydrogen generation.
