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 the Ludwig-Maximilians-University (LMU) in Munich, Germany 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 Department of Informatics of University of Piraeus, Greece, under the supervision of Prof. Yannis Theodoridis. I hold a diploma in Computer Engineering & Informatics and an MSc in Computer Science, both from the Computer Engineering & Informatics Department (CEID), University of Patras, Greece.

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).
