Welcome to my website

I am a postdoc research associate at the Institute of Informatics & Telecommunications of the National Center for Scientific Research (NCSR) "Demokritos", in Athens, Greece, where I work with the Complex Event Recognition group. I On March 2017 I defended my PhD in machine learning. Before joining NCSR I worked as a software developer, and even before that I completed an MSc. in Logic and Computation and a BSc. in Mathematics. My research is mostly on machine learning, artificial intelligence and complex event recognition.

I've been involved in several research projects so far (FP7 and H2020), participating in the development of intelligent systems for challenging application domains, such as transport management, maritime surveillance, credit card fraud detection, assisted living, ambient intelligence and knowledge extraction from social networks.
