About

In 2015 joined as a Research Fellow the Visual Information Laboratory, led by Prof David R. Bull, within the Department of Electrical and Electronic Engineering, University of Bristol, UK. I received my Ph.D. in July 2014 from the Department of Computer Science and Engineering, University of Ioannina, Greece, under the guidance of Prof Lisimachos P. Kondi . My main research interests include topics around the video processing pipeline: acquisition, analysis, compression, and communication, as detailed below. Other side research activities include data and biomedical engineering.
