Research Interests
My general research interests are in the synthesis and characterization of supported metal/metal oxide catalysts. Particular interests are focused on novel synthesis methods for the precise control of the chemical properties of heterogeneous catalytic materials including morphology and corresponding catalytic properties. I utilize a wide array of chemical and spectroscopic characterization techniques of the prepared catalyst materials. Combining catalysts with both physical and chemical characterization can bring us closer to designing new, highly active and selective catalytic materials.
