Background
Schobeiri joined the Dept. of Mechanical Engineering in 1987 and established two gas turbine research areas at Texas A&M University. After coming to Texas A&M University. Schobeiri worked for the Brown Boveri Gas Turbine Division in Switzerland, where he was responsible for the research and development of high efficiency gas turbine engines.
