Over the past decade, scientific and engineering interest in high temperature and supercritical water has been growing quickly as new technologies are developed to harness the unique properties of water at extreme temperatures and pressures. Supercritical water holds great promise in hazardous waste recycling, solar hydrogen production, carbon sequestration and power generation. My major research objective is to provide a fundamental, molecular level understanding of aqueous systems and reactions under high temperature and pressure conditions, and to develop experimental and modeling tools for their study. My primary research focus is on hydrogen-water chemistry in energy generation systems. Another area of my research interests is supercritical water oxidation technology for waste utilization, the process that leaves no harmful by-products in the environment. In my work I make use of a unique flow reactor for high temperature and pressure experiments and a parallel cluster for numerical simulations. My program is ultimately intended to deliver the results of fundamental research to the industry. It should lead to better understanding of high temperature and supercritical aqueous systems, and thus advance their efficient and safe application in many traditional and novel technologies, such as the proposed Canadian GEN-IV Supercritical Water-Cooled Reactor.
