Michael Economides, 64, a University of Houston (UH) energy expert, died of a heart attack on Saturday. Economides was the founding director and chief scientist of the Global Petroleum Research Institute at Texas A&M University before becoming a chemical engineering professor at UH. As a consultant, Economides worked for Chevron Corp., Royal Dutch Shell plc and Petroleos Brasilerio (Petrobras), as well as in Russia and China. He published more than 300 journal articles and more than a dozen books, including The Color of Oil, which he co-authored. He also founded and was editor-in-chief of Energy Tribune, an online publication. In 1969, Economides, then 19, moved to the United States from Cyprus as a Fulbright scholar at the University of Kansas. He became a U.S. citizen in 1982 and went on to receive a doctorate from Stanford University in 1984. He is survived by his wife Christine Ehlig-Economides, also a petroleum engineering expert, and two sons.
