Marta Catalano

I am a Harrison Early Career Assistant Professor in the Department of Statistics at the University of Warwick.
Previously, I was a postdoc at the University of Torino with Pierpaolo De Blasi. I obtained my 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 Bocconi University and of the MIDAS Complex Data Modeling Research Network.
A full version of my CV may be found here.
