Laurea in Scienze Biologiche (Universita’ di Padova) Dottorato (Phd) in Genetica (Universita’ di Ferrara) I was born and grew-up in Mestre (Italy) which is part of the Venetian 'dry-land' (terraferma). I studied at the University of Padova for my first degree. After military service in Rome I won a national competition and obtained a PhD scholarship in Genetics. Although my ‘Dottorato’ was awarded by the University of Ferrara my laboratory work was carried out in the Department of Biology at the University of Padova and in the Department of Genetics at the University of Leicester. I moved to Leicester permanently in 1994.


In my laboratory we are interested in behaviour namely those observable processes initiated by an animal in response to extrinsic and/or intrinsic changes to the environment. Behaviour is a product of the brain; therefore we use it as a convenient tool for the analysis of the nervous system. Over the years my laboratory has been particularly involved in studying a complex behaviour the circadian clock especially (but not exclusively) in the fruit fly Drosophila melanogaster. We are interested in the genes that regulate the clock and we study them by characterising their function by examining their evolution and by analysing their expression. We are also engaged in understanding how clock neurons (neurons expressing clock genes) are organised and how circadian information flows through their network. More recently we have started investigating the inter-relationship between clock and development.

Our laboratory is open to exceptionally motivated students interested in neurogenetics. Particular strengths of our group are: behaviour, biological rhythms, circadian clocks, Drosophila genetics, Cryptochrome. However, any area of neurogenetics will be considered.
