# Uri Shaked

Uri Shaked (Hebrew: אורי שקד; born: 15 June 1943) is an Israeli professor of Electrical Engineering in the Engineering Faculty at Tel Aviv University, specializing in control theory of uncertain systems. In 2017 he was awarded the Israel Prize for engineering research.

## Early life and education

Uri Shaked was born in Petah Tikva, Israel. He studied at "Brenner" high school and received his B.Sc in Physics and Mathematics (1963) and M.Sc in Physics (1966) from the Hebrew University. His Ph.D. degree was received in 1974 from the Department of Applied Mathematics at the Weizmann Institute of Science in Rehovot, Israel. Shaked authored the thesis Synthesis of Multivariable Linear Time Invariant Feedback Control Systems, under the supervision of Prof. Isaac M. Horowitz.

## Career

Shaked was a visiting scholar at Cambridge, UK in the years 1974-1976, and then joined the Department of Engineering at Tel Aviv University as a lecturer. He became a senior lecturer in 1977. In 1981 he was also an adjunct lecturer at the Electrical Engineering Faculty of the Technion, and in 1982 he became an associate professor at the Engineering faculty of Tel Aviv university. In 1983-1984 he was a visiting associate professor at the Department of Electrical Engineering and Computer Science, University of California, Berkeley.
In 1985, Shaked became the head of the Electrical Engineering - Systems Department at Tel Aviv and founded the Tel Aviv University Special Program for Practical Electronic Engineers. He was the chairman of the program, which enabled practical electronic engineers to become professional engineers, until 1987.
Shaked was promoted to a full professor at Tel Aviv University in 1987, and held the chair of Celia and Marcos Maus Professor of Computer Systems Engineering (1989-2013). In 1989-1990 he was a visiting professor at Yale University, and in the years 1993-1998 he was the dean of the Engineering faculty at Tel Aviv University.
In 1999 Shaked was a visiting professor at the Imperial College of Science and Technology, Dept. of Electrical and Electronic Engineering in London, UK. Shaked was on the board of directors of Tel Aviv University in the years 2005-2009. In 2011 he retired from Tel Aviv as professor emeritus.
In 2017 he was elected as chairman of the Israeli section of the Institute of Electrical and Electronics Engineers (IEEE).

## Work

His research interests include linear and non-linear control of uncertain systems; digital control; H-infinity optimization in filtering and control; control and estimation of systems with time delay.
Upon receiving the Israel Prize (2017) for engineering research, his work and its implications were described by the award committee:
   Shaked is considered one of the world’s leading scientists in the field of control theory. The methods developed by Shaked are now widely used in all industries, including the Israeli defense industry. He also made a significant contribution to the expansion of scientific-technological education in Israel and was one of the leaders in the process of establishing academic colleges of engineering that contributed to making academic education accessible to a more diverse range of students.
