Academic Career and Research Areas

The aim of the research work of Professor Koutsourelakis (b. 1975) is to develop computational strategies to model and analyze physical and engineered systems with particular emphasis on continuum mechanics. Dr. Koutsourelakis adopts a cyber-enabled statistical discovery mindset in his research activities. These center around two main themes: a) uncertainty quantification: identification and modeling of stochastic aspects in the mechanics' systems by means of data assimilation and efficient procedures for their analysis and design in the presence of uncertainties, and b) multi-scale phenomena: the discovery of accurate macro-scale descriptions for processes evolving on vastly different spatio-temporal scales.

Professor Koutsourelakis completed his undergraduate studies at the National Technical University of Athens, Greece and obtained a PhD from Princeton University, NJ, USA. He has previously held academic positions at the University of Innsbruck (Leopold-Franzens) (Austria), Cornell University (USA) and Heriot-Watt  University (UK). He was also a research scientist at the Lawrence Livermore National Laboratory, (USA).
