Author of many essays and books on theory and practice in Architectural Conservation. In particular, her research interests have been addressed, on the one hand, to theoretical issues of Conservation from the origin of the discipline up to contemporary debates, while, on the other hand, her studies deal with some issues of the field of practice of conservation with particular reference to ruins or abandoned buildings and urban fabric and to the methods which conservation borrows from other disciplines, such as archaeology. From the collaboration with “Storia urbana”, an interest in the relationship between conservation and transformation in historical city centres in modern times was born, also in relation to destruction due to catastrophic events, such as wars, earthquakes and so on. Her more recent studies have been addressed to the processes of depopulation in small towns and the strategies for conservation and enhancement of abandoned heritage.
