I am a Senior Lecturer (Associate Professor) in Business Analytics at Norwich Business School (NBS) of the University of East Anglia (UEA). I am also a member of the Innovation, Technology and Operations Management Group (ITOM). I am also affiliated faculty with the Centre of Competition Policy (CCP) and an associate faculty member of the Big Data Laboratory of Goethe University Frankfurt, Germany.

Before joining UEA, I worked as Senior Researcher at the Chair for Databases and Information Systems at the Faculty of Informatics and Mathematics of the Goethe University Frankfurt, Germany. I co-founded together with Professor Roberto Zicari the Frankfurt Big Data Lab and I acted as a Director for Analytics and Data Science. I also worked as an Assistant Research Professor (Post.doc) at the Department of Economics of the University of Copenhagen doing research in Experimental Economics and IT as a core member of the iLEE project.

I completed my PhD in 2009 at Copenhagen Business School (CBS), Denmark under the supervision of Prof. Volker Mahnke and I hold an MSc in Engineering from the Royal Institute of Technology (KTH), Stockholm with specialisation in HCI & Information Retrieval (2006). I completed my undergraduate studies at the Athens University of Economics and Business (2004) and I have so far lived and worked in five different countries (Greece, Sweden, Denmark, Germany and UK).

I have also acted professionally as a data scientist in various roles in the industry working for one of the world’s largest car manufacturers and Germany’s biggest lenders in use cases for big data and analytics. My main specialisation is in predictive analytics and in particular the transformation of Business Intelligence and Data Warehousing to support competitive gain through analytical maturity.

I am an active practitioner of analytical methods and tools aiming to increase the impact of my research and some of my work has also been featured in the German media (ARD, HR). I have worked closely with Adastra Germany on developing practical use cases for analytics and big data and have acted as a consultant senior data scientist in providing training to an aspiring team of young data scientists engaged in various projects.

I also contribute on the Operational Data Management Systems Portal which is an industry leading news hub for all things in Big Data, No-SQL and In-Memory data management technologies.
