Pantelis was born in Athens, Greece, in 1985. He received his Diploma in Chemical Engineering in 2007 and an MSc with honours in Applied Mathematics in 2009 from the National Technical University of Athens. In December 2012, he defended his PhD thesis titled "Modelling and Control of Biological and Physiological Systems" at the School of Chemical Engineering, NTU Athens. In January 2013 he joined the Dynamical Systems, Control and Optimization (DYSCO) research unit at IMT Lucca as a Post-Doctoral Fellow. His research interests revolve around Model Predictive Control (MPC), Optimisation, Sampled-data systems, Impulsive Systems and Stochastic MPC. His latest work focuses on fractional-order systems and control and the use of general-purpose GPUs to accelerate numerical optimisation algorithms for large-scale problems.
