Short (informal) Bio
I was born in Veroia, which is located in Macedonia, the northern part of Greece. However, I grew up in the south-west and specifically in the third largest city of Greece: Patras. I stayed in Patras for my undergraduate studies and I received the Diploma (5-years degree) in ECE from the University of Patras in 2011. During my undergraduate studies, I received invaluable advice and was particularly inspired by Professors George Moustakides, Dimitris Toumpakaris and George Bitsoris. In September 2011, I moved to California for my graduate studies. I received a M.Sc. and a Ph.D. degree in EE in 2012 and 2016, respectively, both from Caltech, with a minor in Applied and Computational Mathematics. During these years, I was fortunate enough to have Prof. Babak Hassibi serving as my Ph.D. advisor. I also had the great opportunity to receive advice and guidance by the members of my Ph.D. committee Prof. Joel Tropp and Prof. P. P. Vaidyanathan. I spent the coming two years as a postdoctoral research associate at the Research Laboratory of Electronics (RLE) at MIT, where I was generously supported by Prof. Gregory W. Wornell. In Fall 2018, it was time for me to return to the West Coast and the California sunshine in order to join the faculty at the ECE Department at UC, Santa Barbara. As much as I loved Santa Barbara, in January 2021, I started on a new adventure, moving to Vancouver, Canada, where I am now faculty at the ECE Department UBC.
