Sotiris Bersimis is a Professor at the University of Piraeus, an elected member of the board of directors of the National (Greek) Statistical Institute (GSI) and an elected member of International Statistical Institute. He is the representative of the GSI at the Federation of European Statistical National Societies (FenSTATs) as well as on the board of European Courses in Advanced Statistics (ECAS).

In the past, during the period 9/2020 – 4/2022 he served as the Chair of the Department of Statistics and Insurance Science and as a member of the Senate of the University of Piraeus. In addition, during the period 12/2015 – 1/2019 he served as the President of the Hellenic Organization for Health Care Services Provision while during the period 4/2018 – 1/2019 he has been elected and served as the president of European Healthcare Fraud & Corruption Network (EHFCN). 

He is a PhD holder in Statistics, from the Statistics and Insurance Science Department of the University of Piraeus. He also holds an MSc in Statistics from Athens University of Economics and Business and a BSc in Statistics and Insurance Science from the University of Piraeus. His doctoral research has been funded by a scholarship from the National (Greek) General Secretary of Research and Technology (GSRT). He has also been granted a post-doctoral fellow scholarship by the National (Greek) State Scholarships Foundation (SSF). He has certified knowledge, among others, on “Management of Research, Technology and Innovation”. His research interests are mostly related to the development and implementation of stochastic models for processes monitoring (processes’ quality control, patients’ surveillance, quality of services, etc.), as well as with the theory of runs and patterns. He also works in the fields of data analytics (business, health, insurance analytics). He has published more than 60 papers in international scientific journals (among others, Journal of Quality Technology, Journal of Multivariate Analysis, Annals of the Institute of Statistical Mathematics, Statistics in Medicine, Biometrical Journal) while more than 120 of his papers have been presented in National (Greek) and International Conferences (more than 80 in International Conferences). His work entitled “Multivariate Statistical Process Control Charts: An Overview”, published in “Quality and Reliability Engineering International” journal, is the most cited paper of the journal (May 2022) and one of the most influential papers in Statistical Process Monitoring. For the period 2013 – 2015 he was granted a research fund within the framework of “Excellence II” of the General Secretary of Research and Technology and initiated the research team “Process Monitoring Group” with objective the development of research in the domain of industrial statistics. Finally, his teaching involves mainly “Industrial Statistics”, “Business Analytics”, “Health Analytics & Statistics”, and “Statistical Machine Learning”.
