Marta Catalano

I am an Assistant professor of Statistics at Luiss University in Rome.
Previously, I was a Harrison Early Career Assistant Professor at the University of Warwick. I am also affiliated to the de Castro Statistics Initiative at Collegio Carlo Alberto and to the BayesLab at Bocconi University.
