Welcome to my website

I am an associate professor at the Faculty of Electrical Engineering and Computer Science at the Leibniz University Hannover and member of the L3S Research Center. My research lies in the areas of Data Mining and Machine Learning and can be summarized as developing methods for i) learning over complex data and data stream mining, covering aspects such as adaptive learning, change detection and stability and ii) responsible AI, covering aspects such as fairness-aware learning, data quality and experimentation.

Prior to joining LUH, I was a post-doctoral researcher at LMU, Munich in the group of Prof. Hans-Peter Kriegel. I joined the group in 2010 as a post-doctoral fellow of the Alexander von Humboldt Foundation. I obtained my PhD (2008) from the University of Piraeus, Athens under the supervision of Prof. Yannis Theodoridis. I hold a diploma (2001) and an MSc (2003) in Computer Engineering & Informatics both from the Computer Engineering & Informatics Department (CEID), University of Patras, Greece. In 2007, I co-funded an AI-based news monitoring startup, NeeMo.gr, after winning 1st price in the national 2006 innovation competition. Also, in 2009 I worked as a data mining expert at OTE SA, the national telecommunication provider of Greece.

My work has received several awards, including a Alexander von Humboldt fellowship for postdoctoral studies, a best-student paper award at ICBK 2018 and the 1st place in the 2006 innovation competition in Greece. My research is supported by prestigues funding bodies, including the German Research Foundation (DFG), the Volkswagen Foundation and the European Union.
