## bio

Nicola is an associate professor since 2001. He holds a PhD (00) from Universitat Politecnica de Catalunya, advised by Maria Luisa Bonet and holds an Italian habilitation as full professor in Mathematical Logic since 2012.

Since 22 he is with DIAG (Dept. of Computer, Control and Management Engineering "A. Ruberti" ) in Sapienza, in Rome.

From 05 to 21 he was with the Department of Computer Science, always in Sapienza.

From 01 to 05 Nicola was associate professor at Universitat Politecnica de Catalunya, in Barcelona. Before (01) he was a researcher at School of Mathematics of the Institute for Advanced Studies in Princeton and Postdoc at University of Toronto (02-03).

In 15 and 21 Nicola was visiting scientist at Simons Institute for Theory of Computing. UC-Berkeley and in 15 at Tokyo Institute for Technology.
