Mete Avni Sözen (22 May 1930[1] – 5 April 2018)[2][3] was Kettelhut Distinguished Professor of Structural Engineering at Purdue University, Indiana, United States from 1992 to 2018.
[4] 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.
[8] 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.
