My research interests are in the areas of plasma conversion, plasma diagnostics, and microfabrication. Our most recent project involves the plasma conversion of carbon dioxide to CO and O₂. Plasma reactors are an attractive alternative to conventional conversion processes since the electrons and active species in the plasma can stimulate dissociation even when the bulk gas is near room temperature and at atmospheric pressure. They are also more energy efficient. The CO obtained by splitting CO₂ could be combined with hydrogen to form synthesis gas for the production of value-added fuels and chemicals.
