SUMMARY

Having a strong Physics background (B.Sc.), a M.Sc. on Computational Science and a PhD on Computer Science, Dr. Dimitrios Tzimeas is keen on the algorithmic design of complex and multidimensional problems. His PhD work was focused on the A.I. simulation of human creativity. In this research he applied Genetic Algorithm in order to find optima in a multicomplex landscape. In order to achieved this he moved to a novel GAs technique, the damped oscillator GAs, introducing the physical model of a damped oscillator in the GAs fitness function. Since 2014 he is an unremunerated Postdoc research member of the Astrophysics Spectroscopy team of National and Kapodistrian University of Athens, Greece. During this research he developed ASTA software, an approach in analysis and process of astronomy data. The combination of long experience in Physics with a deep understanding in Computer Science makes him the key person of the team having the principal role of interpreting a real world problem into algorithmic design. His research work attached equally to Astrophysics, Computational Science and Artificial Intelligence/Computer Science assures that he has the skills to communicate with each individual member of this interdisciplinary team in a mutual language regardless scientific specialty.
