Prof. Konstantinos N. Raftopoulos is an Associate Professor at the Cracow University of Technology, where he has been a faculty member since 2016. He received his Diploma in Physics from the National and Kapodistrian University of Athens in 2003, his Master’s degree in Energy Production and Management from the National Technical University of Athens in 2005, and his Ph.D. in Polymer Physics from the National Technical University of Athens in 2011. From 2012 to 2014, he was a postdoctoral researcher at the Cracow University of Technology. He then worked at the Department of Physics of the Technical University of Munich, first as a TUFF Fellow from 2014 to 2015 and then as a Scientific Associate from 2015 to 2016. His research focuses on polymer physics, especially glass transition phenomena, molecular mobility, water–polymer interactions, stimuli-responsive polymers, polymer nanocomposites, and the relation between molecular structure, thermal history, and macroscopic material behaviour.
