[ABE-L] Fwd: ISBA-BNP June 2026 special interview webinar: Eugenio Regazzini

[Hedibert Lopes]

Eugenio Regazzini é um estatístico italiano conhecido por suas
contribuições importantes à *estatística Bayesiana*, à teoria da
probabilidade e à *estatística Bayesiana não paramétrica*. Ligado durante
grande parte da carreira à University of Pavia, Regazzini faz parte da
tradição probabilística italiana inspirada por Bruno de Finetti e sua visão
subjetivista da probabilidade. Seus trabalhos abordam temas como
permutabilidade, inferência preditiva, processos estocásticos e os
fundamentos matemáticos do pensamento Bayesiano.

Regazzini ficou especialmente reconhecido por pesquisas pioneiras
sobre *processos
de Dirichlet* e outras *"random probability measures"*, ajudando a
construir bases teóricas sólidas para a inferência Bayesiana não
paramétrica. Seus estudos sobre funcionais do processo de Dirichlet e
estruturas preditivas aproximaram a modelagem Bayesiana da teoria clássica
da probabilidade e de métodos analíticos, influenciando desenvolvimentos
posteriores em modelos de amostragem de espécies e processos estocásticos
permutáveis. Além da pesquisa, também teve papel importante na formação de
novas gerações de probabilistas e estatísticos Bayesianos, ampliando a
tradição Bayesiana italiana na estatística moderna.

DATE & TIME: 15:00 UTC on Thursday June 4th, 2026. Note that 15:00 UTC
corresponds to 11:00 US Eastern (EDT) and 17:00 Central European (CEST).

SPEAKER: Eugenio Regazzini (University of Pavia)

DESCRIPTION: This special interview webinar features a recorded interview
with Prof. Eugenio Regazzini, conducted by Antonio Lijoi and Igor Prünster.
Regazzini retraces his scientific itinerary from his student years at
Bocconi in the late 1960s, when his thesis on hypothesis testing was
assigned in an Italian landscape still dominated by Gini's descriptive
tradition. He describes the state of probability and statistics in Italy in
the late '60s and '70s, recalling the small network of probability chairs
of the time and the "return" of de Finetti's ideas to Italy after Savage
had championed them in the United States. He then recounts his
long-standing collaboration with Donato Michele Cifarelli and the spark
that led them into Bayesian nonparametrics — a 1935 abstract by de Finetti
on "*perequazione"*, combined with Ferguson's work on the Dirichlet process
— which gave rise to their study of the distribution of the mean of a
Dirichlet random measure (the Cifarelli–Regazzini identity). The interview
closes with a reflection on what it means to be a subjectivist in the
spirit of de Finetti, and with reading recommendations for young Bayesians.

The interview is in Italian, with carefully curated English subtitles.
Following the recording, there will be a live discussion with Prof.
Regazzini.

Best regards,
