    Research Scientist (Co-affiliated with Prof. Van Vliet and Prof. Tuller at MIT)

    Education:
    Ph.D. Materials Science and Engineering, University of Florida, Gainesville, FL
    B.S. Materials Science and Engineering, New Mexico Institute of Mining and Technology, Socorro, NM

    Sean’s interests lie in determining and controlling defects at interfaces and in bulk materials to manipulate electrochemomechanical properties. For example, in solid oxide fuel cells (SOFCs) and three way catalysts (TWCs), there is an exchange of oxygen between the environment and the material. The rate of this exchange is crucial to maximizing SOFC power and TWC efficiency and it has the potential to be modified by controlling the interfacial and bulk electronic and ionic defect nature and concentration. Research is currently underway to examine the relationship between defect concentrations in high temperature oxide bulk and thin film materials to electrical and mechanical properties using electrochemical (impedance spectroscopy), mechanical (dilatometry, nano-indentation), and chemical (thermo-gravimetry) measurements.

    Tobias's research is focused on oxygen reduction kinetics (ORK) of mixed electronic and ionic conducting perovskite ceramics. One goal is to find correlations between structural or chemical properties and ORK as well as the effect on long time durability of these materials in solid oxide fuel cell operation condition.

One of the main topics of his research in the last years has been the study of Oxygen surface exchange kinetics of mixed ionic-electronic thin film cathode materials and their ageing process related to surface modifications induced by cation diffusion, as well as thin film engineering to enhance their performance and durability.

    My research focuses on atomic-scale modeling of surface reactions that occur on iron sulfide films. These surface films play a major role in degradation of sub-sea infrastructure of off-shore oil platforms and understanding the thermodynamic and kinetic fundamentals of surface reactions can pave the way for design of tougher materials for such extreme environments. In particular, I am looking at the effect of surface and defect chemistry on the rates of unit processes such as interfacial charge transfer and ionic diffusion using DFT and other higher-scale modeling methods.
