Marta Catalano

I am a postdoctoral researcher at the University of Torino working with Pierpaolo De Blasi. Previously, I obtained a PhD in Statistics at Bocconi University, under the supervision of Antonio Lijoi and Igor Prünster. I am also member of the “de Castro” Statistics Initiative at Collegio Carlo Alberto, of the BayesLab at the Bocconi Institute for Data Science and Analytics (BIDSA) and of the MIDAS Complex Data Modeling Research Network.
A full version of my CV may be found here.
