Mr. Apostolos Zdagkas

Generation Detection and Light-Matter Interactions of Focused Doughnut Pulses

Short CV
Apostolos obtained his 4-year Degree in Physics (with honours) with emphasis in Solid State Physics from the National and Kapodistrian University of Athens, Greece in 2013. In 2015, he received his master degree in Materials Physics, at the same Institution. Apostolos joined the Optoelectronics Research Centre as a PhD student in January 2017.
