## Early life and education

Emilia Fridman was born in Kuibyshev, USSR. During the years 1976-1981 she studied Mathematics, B.A. and M.Sc (with distinction) at Kuibyshev (Samara) State University. Her Ph.D. degree was received in 1986 in Mathematics from Voronezh State University (USSR). Fridman authored the thesis Integral Manifolds of Singularly Perturbed Time-Delay Systems and Their Applications, under the supervision of Prof. Vadim Strygin.[2][3]

## Career

Fridman was a researcher at Kuibyshev Polytechnical Institute, USSR in the years 1981-1982. She joined Kuibyshev Institute of Railroad Engineers, Department of Mathematics, as Assistant Professor in 1985, and in 1989 was promoted to Associate Professor.

In 1992 Emilia moved with her family to Israel, and joined the Department of Electrical Engineering and Systems at Tel Aviv University. She worked on various programs supported by the Ministry of Absorption, starting from Senior Researcher in 1993, and becoming a Principal Research Associate (parallel to Associate Professor) in 2002. She was promoted to Full Professor in 2012.[3]

During the years, Fridman has held visiting positions in many institutions, including: Weierstrass Institute for Applied Analysis and Stochastics in Berlin (Germany), INRIA in Rocquencourt (France), Ecole Centrale de Lille (France), Valenciennes University (France), Leicester University (UK), Kent University (UK), CINVESTAV (Mexico), Zhejiang University (China), St. Petersburg ITMO (Russia), Melbourne University (Australia), Supelec (France), KTH (Sweden).[4]

## Research work

Emilia’s research interests include time-delay and singularly perturbed systems, sampled-data and network-based control, control of partial differential equations (PDEs) and nonlinear control. She has pioneered a time-delay approach to sampled-data control. This approach became popular in networked control systems, allowing communication delays to be larger than the sampling intervals.

She has also introduced the descriptor method for time-delay systems and robust control that led to efficient analysis and design methods. Additionally she has introduced the Lyapunov-Krasovskii method for systems with fast-varying delays (without any constraints on the delay derivative). Fridman has pioneered the linear matrix inequalities approach to robust control of PDEs and network-based control of PDEs.[5]

According to Google Scholar (August 2020) her h-index is 63[6] and she is the most highly cited woman in control theory.[7]

## Professional experience

Fridman is a fellow of IEEE Control Systems Society. She is an Associate Editor of Automatica,[8] and has been an Associate Editor in leading control journals: IMA J. Control & Information,[9] SIAM J. Control & Optimization.

Fridman was nominated as Highly Cited Researcher in 2014 by Thomson Reuters (Web of Science).[10]

In 2017 she was elected as a council of the International Federation of Automatic Control.[11]

Since 2018, she is incumbent for Chana and Heinrich Manderman Chair on System Control at Tel Aviv University.[3]

In 2021 she was awarded the IFAC Delay Systems Life Time Achievement Award[12] and the Kadar Family Award.[13]

## Publications

Prof. Fridman has authored more than 170 journal papers and two monographs: Fridman, Emilia. Introduction to Time-Delay Systems: Analysis and Control. Birkhauser. Systems & Control: Foundations & Applications, 2014.;[14] Liu, Kun, Fridman, Emilia, Xia, Yuanqing. Networked Control Under Communication Constraints: A Time-Delay Approach.
