The depletion of natural resources, rising fuel costs, and increasingly stringent environmental regulations have created a need for new and diverse forms of energy. Heterogeneous catalysis has played and will continue to play an important role both in the generation and use of energy to ensure a sustainable future, but a number of open questions remain to exploit the full potential of such catalytic systems. In order to do this, one needs not only to understand, but also to control materials at the nanometer length scale and far away from thermodynamic equilibrium.
In my research group, we model such systems from an atomistic (using ab initio quantum chemistry tools) and macroscopic (using Monte Carlo and Transfer Matrix methods) point of view. We also link these methods with corresponding multi-scale models. Our work is done in close collaboration with experimentalists. Some areas of interest to me are listed below.
- Heterogeneous Catalysis in High Electric Fields
- Theory of Surface Processes
Jean-Sabin McEwen earned his B. Sc. in Physics at McGill University, Canada. He then went on to earn his M. Sc. and his Ph.D. in Physics at Dalhousie University, Canada. He spent about two years as a postdoctoral fellow in Belgium at the ULB and three years in Belgium at the F.R.S.-FNRS. He went on to obtain a position as research assistant professor at the University of Notre Dame for two years. He is now an assistant professor at Washington State University.

The collaborative research done between the McEwen and Wang groups is highlighted on the cover of the October issue of ACS Catalysis, which illustrates a Pd/Fe catalyst and its hydrodeoxygenation capability using m-cresol. Read more about Dr. McEwen's research on biofuels
