Monica Mazzolani and Antonio Troisi attained their Bachelor in Architecture at the University of Genoa. In 1988 they began working with Giancarlo De Carlo at his Milan studio and from 1994 they became project associates. In 2002 the studio became Giancarlo De Carlo and Associates, with the aim of concluding a long cycle of collaboration and participation in project planning and methodology, and of bringing current works to completion.
In December 2005 they founded MTA Associates, with the same intention of research and elaboration in the field of architecture and urban planning.
The studio is committed to developing in a number of fields and to varying scales, managing the renovation of buildings of particular architectural interest and of new build projects in outstanding urban and natural settings, territorial plans and, more recently, landscape planning.
