Periklis Andritsos is an Associate Professor at the University of West Attica and the Department of Informatics and Computer Engineering. In the past he has taught both in Canada (University of Toronto) and in European Institutions (Italy and Switzerland). He holds a Masters and PhD from the Department of Computer Science at the University of Toronto in Canada, where he also stayed for post-doctoral studies. In his research, he deals with the management and extraction of knowledge from large data sources and more specifically with the clustering of categorical (non-numerical) data. His research work with the LIMBO algorithm is a benchmark in this research area with its use to extract useful information for database redesign. He is a co-founder of two start-up companies, Thoora Inc. and Odaia.ai. The first has received the TechCrunch 50 award as one of the best emerging companies of 2009 worldwide and is the owner of 4 patents. In recent years, he has been dealing with the application of deep learning and Process Mining technologies to data referred to as Customer Journey Maps, which provides information on the user experience when a service is consumed. His work in this field has been recognized as the first to deal with the subject and has been distinguished with two best paper awards at international conferences. The techniques proposed in them have been used both in the company Odaia.ai and in bank applications (National Bank of Denmark) and in urban transport information systems (Municipality of Lausanne, Switzerland).
