Fabrizio Ruggeri talks about ISI membership
I started my scientific activity a long time ago, in the 1980s, and I have seen many changes since then. As a Bayesian statistician, I still remember the days before MCMC (Markov chain Monte Carlo) and then the blossoming of Bayesian works after MCMC became so popular. Six Sigma, Big Data, Data Science are concepts which I have encountered over the years, and they opened new perspectives and challenges for a mathematical statistician like me. Changes also occurred in my knowledge of statistical associations. I started with SIS and ASA, the Italian and US statistical associations, and with UMI (the Italian Mathematical Union) due to my Italian origin and affiliation and US studies. Then I broadened my interests to specialised international societies, such as IMS (Institute of Mathematical Statistics), ISBA (International Society for Bayesian Analysis) and ENBIS (European Network for Business and Industrial Statistics), and I eventually became President of the last two in 2012 and 2005, respectively (as I did with ISBIS in 2019). Finally, I took the last step, and I became an ISI Elected Member (and then Council Member, Vice President, and President-Elect), entering the most important statistical organisation at international level. As you can see, I continued to broaden my horizons, expanding my knowledge about Statistics and statisticians. And ISI is THE perfect place for broadening someone’s views. This is where I met, for example, people working in Official Statistics and I learned (not enough, sorry!) about the problems they are facing and how they are tackling them. ISI is the place where I made new friends and where new collaborations began.
