Presentation

Mihai Telescu received a Doctorate in Electronics from the University of Brest, France in 2007, he was a post doc researcher with the EMC Group at the Politecnico di Torino, Italy between 2008 and 2009. He has been an Associate Professor with the UBO ever since. His research interests include linear and non-linear macromodeling, model order reduction, system identification, CAD and related topics. He focuses primarily on Inout/Output mathematical descriptions of systems enabling fast simulation. These issues are crucial in signal integrity for example where smart surrogate models are used for both channels (interconnects) and buffers. Since 2015 he is also conducting research in telecommunications with a focus on the design of non-linear predistorters. Predistorter design basically amounts to an inverse system identification problem where the aim is to compensate the nonlinear behavior of a channel. His more recent research interests include stochastic analysis and, in particular, robust problem solving. He is currently developing a toolbox for system optimization in the presence of uncertainties. Mihai Telescu chaired the 22nd and the 23rd editions of the IEEE Workshop on Signal and Power Integrity in Brest and respectively, in Chambery. He is an associate editor at IEEE Transactions on Components, Packaging and Manufacturing Technology.
Mihai Telescu a obtenu un diplôme d'ingénieur en électronique et télécommunications de l'Université polytechnique de Timisoara, en Roumanie, en 2003, un DEA de l'Université de Rennes 1, en France, en 2004 et un Doctorat en électronique de l'Université de Brest (UBO), en France, en 2007. Il a été chercheur post-doctoral au sein du groupe EMC du Politecnico di Torino, en Italie, entre 2008 et 2009. Il est actuellement maître de conférences à la Faculté des Sciences et Techniques de l'UBO et membre du laboratoire LabSTICC. Ses recherches portent sur la macromodélisation linéaire et non-linéaire, la réduction de l'ordre des modèles, l'identification des systèmes, la CAO et les sujets connexes. Une grande partie de ses travaux portent sur la modélisation mathématique des systèmes à des fins de simulation rapide. Ces questions sont cruciales pour l'intégrité des signaux, par exemple. Depuis 2015, il mène également des recherches dans le domaine des télécommunications, sur les prédistordeurs non-linéaires. La conception de prédistordeurs peut être vue comme un problème d'identification de système inverse où le but est de compenser le comportement non linéaire d'un canal. Ses intérêts de recherche plus récents incluent l'analyse stochastique et, en particulier, la résolution robuste de problèmes. Il développe actuellement une tool-box pour l'optimisation de systèmes en présence de d'incertitudes. Mihai Telescu a présidé la 22e et la 23e édition de l'IEEE Workshop on Signal and Power Integrity, à Brest et, respectivement, à Chambéry. Il est éditeur associé de IEEE Transactions on Components, Packaging and Manufacturing Technology.
