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 learning over complex data and data streams. I am also interested in responsible data science, covering aspects like fairness-aware learning, reliability, 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 from the University of Piraeus, Athens under the supervision of Prof. Yannis Theodoridis. I hold a diploma and an MSc in Computer Engineering & Informatics both from the Computer Engineering & Informatics Department (CEID), University of Patras, Greece. In 2007, I funded an AI-based news monitoring startup, NeeMo.gr, after winning 1st price in the national 2006 innovation competition.

I am looking for talended PhD students on data stream mining/ adaptive machine learning and fairness-aware learning. If interested, please sent me an email with all supporting documents (CV, certificates, transcripts, motivation letter, referees).
