**Meet the editor**

After graduating in Fuel Engineering from Leeds University, England, I was appointed British Coke Research Association Fellow, and in 1973 I was awarded my Ph.D. After graduation I worked at an oil refinery and in other research establishments in the UK and Syria. In 1980 I spent an academic year at the Technical University of Aachen, and in 1990 I was awarded the Fulbright schol-

arship and spent an academic year at the University of Pittsburgh. For the last 40 years I have been a professor of petroleum refining at Al-Baath University, Syria, and Director of Quality Assurance (since 2003). My publications include research papers on chemical engineering and on quality assurance in education, literature, and general culture. I have also written several textbooks on petroleum refining, metallurgy, sources of energy, and a dictionary of petroleum terms.
