Research Interests

Gas turbines produce approximately 35% of the total electricity generation in the U.S and their efficiency largely depends on the gas temperature at the inlet; the higher the temperature, the higher the efficiency. My research focuses on the high-temperature oxidation and aqueous corrosion of the ultrahigh temperature refractory metal alloys using electron microscopy and simulation techniques.
