Ezio Rosato was born and grew-up in Mestre, Italy, before studying for a ‘Laurea’ at the University of Padova.
After military service in Rome, Ezio won a national competition and obtained a PhD scholarship in genetics. Although the ‘Dottorato’ was awarded by the University of Ferrara, the 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.
Professor Rosato moved to Leicester permanently in 1994.
Professor Rosato’s laboratory is 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 can be used as a convenient tool for the analysis of the nervous system.
Over the years the laboratory has been particularly involved in studying a complex behaviour known as the circadian clock, especially (but not exclusively) in the fruit fly Drosophila melanogaster. The group are interested in the genes that regulate the clock and study them by characterising their function, by examining their evolution, and by analysing their expression.
They are also engaged in understanding how clock neurons (neurons expressing clock genes) are organised and how circadian information flows through their network. More recently studies have started investigating the interrelationship between clock and development.
