Academic career

Sozen earned his undergraduate education at the Engineering School of Robert College in Istanbul (1951), and his master's (1952) and doctoral degrees (1957) from the University of Illinois at Urbana–Champaign. He earned his Ph.D. under the direction of Chester P. Siess and Nathan M. Newmark performing experimental studies to develop theories governing the shear strength of prestressed concrete girders.[5] He then began his academic career at University of Illinois at Urbana–Champaign where he served on the faculty from 1957 through 1992.[6]

Earthquake engineering

With funding from the National Science Foundation and technical support from MTS Systems Corporation Sozen, Shunsuke Otani, Polat Gulkan, and Norbert Nielsen developed the first earthquake shaking simulators in the United States in 1967, which was housed at University of Illinois.[8]

Other contributions

Besides his academic interest in the development of design codes for concrete structures, Sozen was notable for his contributions to the official post 9/11–government studies of terrorist attacks, including the Oklahoma City bombing, and The Pentagon.[9][10] Sozen also led a team that created an engineering simulation of American Airlines Flight 11 crashing into the North Tower of the World Trade Center. The computer–animated visualizations were made entirely from the simulation data.[11]

In 1977, he was elected to the National Academy of Engineering.[12]
