Biographical sketch

Andrea Cerioli received his Ph.D. in Statistics from the Department of Statistical Sciences of the University of Padua in 1992. He has been Professor of Statistics at the University of Parma, Italy, since 2002. He is currently affiliated with the Department of Economics and Management. He was President of the Board of Studies of the Faculty of Economics of the University of Parma in the period 2009-2012 and member of many other boards since then.

He is author or coauthor of more than 100 scientific peer-reviewed scientific works, most of them published in international journals or books. He is also a coauthor of the book "Exploring Multivariate Data with the Forward Search" and a co-editor of the book "Data Analysis, Classification and the Forward Search", both published by Springer-Verlag.

In the years 2011-2015 he was Editor-in-Chief of the journal “Statistical Methods and Applications” (Springer), for which he had served as a Co-editor in the years 2008-2011. He is currently an Editor of the journal “Advances in Data Analysis and Classification” (Springer).

He was President of the Classification and Data Analysis Group (CLADAG), a Section of the Italian Statistical Society, in the years 2009-2011. In the years 2011-2017 he was a member of the Council of the International Federation of Classification Societies.

He chaired the Local Organizing Committee of the CLADAG 2005 Conference, hosted by the University of Parma. He has served and is still serving on the Scientific Program Committee of many international conferences. He has been invited to give plenary talks and to organize specialized sessions at many international scientific conferences.



A large part of his research activity has focused on the development of robust methodologies for data analysis, both under the approach called “Forward Search” and other high-breakdown techniques, with special emphasis on:

  • multivariate outlier detection and testing, when masking and swamping are present
  • consistency, robustness and efficiency of estimators
  • robust classification and clustering
  • the relationships among alternative approaches
  • the properties of methods under elliptical and non-elliptical distribution models.

He also studied the effect of spatial autocorrelation on association tests between categorical variables and the properties of clustering methods.

His more recent research activity includes:

  • The properties of Benford’s Law for the distribution of digits arising in international trade and the development of efficient statistical procedures for testing this law;
  • Tempered (Positive) Stable distributions and the development of computationally efficient methods for estimating their parameters.

From the point of view of applications, he is mainly interested in applying methodologies to solve problems of major economic impact for businesses and the whole Society. The main application area in the last few years has been the detection of data manipulations in international trade, which has also been the main motivation for the development of the new methodologies described above.
