Erik I. Verriest received the degree of ‘Burgerlijk Electrotechnisch Ingenieur’ from the State University of Ghent, Ghent, Belgium in 1973, and the M.Sc. and Ph.D. degrees from Stanford University in 1975 and 1980, respectively.

He was with the Control Systems Laboratory and the Hybrid Computation Centre, Ghent, Belgium, working on process simulation and control in 1973-74. His doctoral research at Stanford was on the algebraic theory and balancing for time varying linear systems and sensor arrays. He joined the faculty of Electrical and Computer Engineering at Georgia Tech in 1980 and spent the 1991-92, 1993-94 and 1994-95 academic years at Georgia Tech Lorraine. He was on leave at the KU Leuven, Leuven, Belgium in the Fall of 2008 and the Julius Maximilian Universität in Wűrzburg, Germany in the Fall of 2016. He has also held short visiting positions at the University of South Florida (1980), Stanford University (1981), and the Université catholique de Louvain, Louvain-la-Neuve, Belgium (1991).

He taught 28 different topics in his 37 years at GT, ranging over mathematics, stochastics, signal analysis and processing, communication, and control.

His earlier research centered on the application of the theory of systems over finite fields in cryptography, data compression, sensitivity analysis of array algorithms with applications in estimation and control, algorithms for optical computing. His present interests are in mathematical system theory. He contributed to the theory of periodic and hybrid systems, delay – differential systems, model reduction for nonlinear systems, control with communication constraints, locomotion and optimal control. He served on several IPC’s and is a member of the IFAC Committee on Linear Systems and the IFAC Committee on Optimal Control. He is director of the Mathematical System Theory Laboratory (MASTLab), a Fellow of the IEEE and an elected member of the Royal Flemish Academy of Belgium for Science and the Arts. He is an enthusiastic problem solver (SIAM Review and the American Mathematical Monthly): over 100 problems solved). In 2017 he received the ECE Distinguished Faculty Achievement Award and enjoys being a hiker and a canyoneer.
