About me

A full pdf version of my CV is available here.
I am a Researcher (Italian RTD-A) at the Bocconi Institute for Data Science and Analytics , at Bocconi University, Italy.

My research interests are in Bayesian Nonparametrics, Probabilistic Machine Learning, Applied Bayesian Modelling and Computational Statistics with a focus on
dependent random measures,
clustering, random partition models and network data
change-point detection and dynamic models,
biostatistics, behavioural and financial econometrics applications.

I am the Chair of the Junior Section of ISBA (j-ISBA) .


Until July 2023, I was a Research Fellow at the Agency for Science, Technology and Research (A*STAR) and member of the Division of Biomedical Data Science (BiDS), led by Prof. Maria De Iorio, at the National University of Singapore (NUS), in Singapore. Until January 2022, I was a PhD student in Statistics at Bocconi University, Italy, under the supervision of Prof. Antonio Lijoi and Prof. Igor Prünster.
