Beatrice (Bea) Franzolini


A full pdf version of my CV is available here.

I am a Research Fellow at the Agency for Science, Technology and Research (A*STAR), in Singapore, where I am working under the mentorship of Prof. Maria De Iorio. Prior to joining A*STAR, I was a PhD student in Statistics at Bocconi University , Italy, under the supervision of Prof. Antonio Lijoi and Prof. Igor Prünster.

I am a member of the Division of Biomedical Data Science (BiDS) of the NUS Yong Loo Lin School of Medicine, in Singapore, of the BayesLab at the Bocconi Institute for Data Science and Analytics (BIDSA), and of the Complex Data Modeling Research Network.

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

My research interests are in Bayesian nonparametrics, Bayesian methodology, and biostatistics.
