Maria Kateri, RWTH Aachen, Germany   
Maria Kateri is Professor of Statistics and Data Science at the RWTH Aachen University, Germany. She holds a Diploma in Mathematics from the University of Ioannina, Greece, a M.Phil in Statistics and Modelling Science from the University of Strathclyde in Glasgow, UK, and a PhD in Mathematics from the University of Ioannina. She has served as assistant and associate professor at the Department of Statistics and Insurance Science of the University of Piraeus, Greece, and as associate professor at the Department of Mathematics of the University of Ioannina. Her expertise is mainly in the areas of categorical data analysis and reliability. She has contributed to the analysis of contingency tables and to modelling of ordinal data, employing tools of statistical information theory, algebraic statistics, and Bayesian approaches. Moreover, she works on accelerated life testing under censoring, being also involved in engineering applications. Since 2017, she is Editor of Metrika.

Dimitris Rizopoulos, Erasmus University Rotterdam, The Netherlands   
Dimitris Rizopoulos is a Professor in Biostatistics at the Erasmus University Medical Center. He received an M.Sc. in statistics (2003) from the Athens University of Economics and Business and a Ph.D. in Biostatistics (2008) from the Katholieke Universiteit Leuven. Dr. Rizopoulos wrote his dissertation and several methodological and applied articles on various aspects of models for survival and longitudinal data analysis. He is the author of a book on joint models for longitudinal and time-to-event data. He has also written three freely available packages to fit such models in R under maximum likelihood (i.e., package JM) and the Bayesian approach (i.e., packages JMbayes2 and JMbayes). He currently serves as co-Editor for Biostatistics.

Fiona Steele, London School of Economics, UK   
Fiona has been Professor of Statistics at LSE since 2013. Her research interests are in developments of statistical methods that are motivated by social science problems. Her areas of expertise include longitudinal data analysis, multilevel and latent variable modelling, and models for complex covariance structures. She has worked on a range of applications in demography, education, family psychology and health. Fiona was elected a Fellow of the British Academy in 2009.

Ernst Wit, Università della Svizzera italiana in Lugano, Switzerland   
Professor Ernst C. Wit is Professor of Statistics and Data Science at the Università della Svizzera italiana in Lugano, Switzerland. He obtained PhDs in Philosophy (1997, Penn State) and Statistics (2000, University of Chicago) in the US. From 2000 until 2005 he was in the Statistics Department at the University of Glasgow, where he became a Reader. In 2005 he became head of the Medical Statistics Unit at the University of Lancaster as full professor. From 2008 until 2018 Wit was at the University of Groningen, for the last 4 years as head of the Mathematics Department. In 2017 he was co-organizer of the 32nd IWSM in Groningen. Since 2018 he is in Switzerland, where he has continued to work on methodological development in high-dimensional inference with a specific focus on network modelling, such as graphical models and relational event models. He continues to work in biostatistical applications, but recently has also started to focus on socio-economical applications. He is the author of 130 peer-reviewed publications. He has served as the President of the European Bernoulli Society and as member of the Board of Directors of the International Biometrics Society. He was president of the Dutch Biostatistics Society. Furthermore, he advises the Ministry of Internal Affairs in the Netherlands on statistical matters relating to elections and referendums since 2014.
