Research in our group is focused on two principal objectives: to reduce the environmental impacts of fuel use and to develop renewable fuel sources. Central to these goals is the application of catalysis. In addition to the synthesis of novel catalysts, studies are conducted to probe catalyst structure, mode of action and deactivation mechanisms.

Research is conducted at the UK Center for Applied Energy Research (CAER) in collaboration with a number of other university departments and external institutions, and is performed by both students and CAER staff. Collaboration between CAER and the various science and engineering departments at UK allows students to receive traditional graduate and undergraduate education, while being exposed to the unique multidisciplinary environment at CAER. For an overview of the main topics currently being researched please refer to the CAER website:
