Ivan Markovsky is an ICREA research professor at the International Centre for Numerical Methods in Engineering (CIMNE). His background is in electrical engineering with a PhD from the Katholieke Universiteit Leuven, Belgium, in 2005. From 2006 to 2012 he lectured and did research at the School of Electronics and Computer Science of the University of Southampton, U.K. He continued his academic career with a 10-years research professor mandate 2012-2022 at the Electrical Engineering Department of the Vrije Universiteit Brussel, Belgium. After a 3-month visiting professor position at the Automatic Control Laboratory (IfA) of the ETH Zurich, Switzerland, he moved in 2023 to CIMNE. His expertise is in structured low-rank approximation, system identification, and data-driven control. On these topics he has 110 peer-reviewed papers, 11 book chapters, and 2 monographs.
In 2011, he was awarded an ERC starting grant on the topic of structured low-rank approximation.

Research interests

The objective of my research is unsupervised data-driven analysis and design of dynamical systems. The classical paradigm splits the problem into model identification and model-based design. In general, there is no separation principle for modeling and design, so that the two-stage approach may be suboptimal. I am investigating an alternative direct data-driven paradigm that combines modeling and design into one joint problem. In 2010, I proposed a solution approach for data-driven design based on structured low-rank approximation (ERC starting grant). More recently, I investigated convex relaxation, subspace, and regularization methods. Current topics of interest are data-driven methods for nonlinear, time-varying, and distributed systems. Besides data-driven design, I am interested in methods for teaching and learning that are effective in training critical thinking and creativity. I am an advocate of the open peer review as an alternative to the traditional closed review system.
