Fabrizio Ruggeri

Fabrizio Ruggeri is an Italian statistician. His work focusses on Bayesian methods, specifically robustness and stochastic process inference. He has done innovative work on the sensitivity of Bayesian methods and incompletely specified priors. He has also worked on Bayesian wavelet methods, and on a vast variety of applications to industrial problems. His publications include well over 150 refereed papers and book chapters, as well as six books.

Education and career

Ruggeri was born in Reggio nell'Emilia in northern Italy on 1 May 1956. He received his B.Sc. in mathematics at the University of Milan in 1982. From 1983 to 1988, he took on a series of jobs in the industry. He moved to the US to continue study in 1988, receiving a M.Sc. in statistics from Carnegie Mellon University in 1989, and his PhD in statistics from Duke University in 1994. ^[1] In 1988, he also became Researcher at Consiglio Nazionale delle Ricerche (CNR – National Research Council)  at Istituto di Matematica Applicata e Tecnologie Informatiche (IMATI – Institute of Applied Mathematics and Information Technology) in Milano, Italy, where he spent all his career until his formal, but not substantial, retirement in May 2023. Between December 2001 and May 2023, Ruggeri held the position of Research Director, (equivalent to Full Professor in universities). ^[2]

Ruggeri has had several visiting researcher and adjunct appointments at universities and institutes around the world including: Adjunct Faculty member at the Polytechnic University of Milan between 1995 and 2003; Faculty member of  Ph.D. programs in Mathematics and Statistics at University of Pavia and University of Milano Bicocca (1999-2024); Adjunct Professor (2013-2022), Queensland University of Technology, Brisbane, Australia; Visiting Faculty, Business School, George Washington University, USA (Fall 2014 and Spring 2024); Program Leader, SAMSI, Durham, USA (August 2019-May 2020);  Chair of Excellence at University Carlos III and ICMAT (Comunidad de Madrid, Spain May -October 2017); Foreign Faculty member (2012-2020) of the Ph.D. program in Statistics, University of Valparaiso, Chile; Research Associate, Electricité de France, Paris, France (September -October 2016). ^[1]

Since retirement in May 2023, Ruggeri has been  a Senior Fellow at CNR-IMATI ^[1] . He is also an Academic Advisor (2023-2026) at the  Institute of Statistical Sciences, Academia Sinica, Taipei, Taiwan. ^[3]

Ruggeri is an elected member of the International Statistical Institute (ISI) ^[4] and a fellow of the American Statistical Association (ASA), ^[5] the International Society for Bayesian Analysis (ISBA) ^[6] and the Institute of Mathematical Statistics (IMS). ^[7] He is the first recipient of the Zellner Medal ^[8] by ISBA. He was the president of the ISBA in 2012 ^[9] and the European Network for Business and Industrial Statistics (ENBIS) for the period 2005–2006. ^[10] He was also President of the International Society for Business and Industrial Statistics (ISBIS) for the period 2019-2021. ^[11] He was one of the Vice-Presidents of the ISI for the period 2017-2021 and he is currently President-Elect for the period 2023-2025; he will be President for the period 2025-2027. ^[12] Ruggeri is a former Editor-in-Chief of Applied Stochastic Models in Business and Industry ^[13] and is one of the Founding Editors of Wiley StatsRef -Statistics Reference Online ^[14] .
