"Nothing in biology makes sense except in the light of evolution". Dobzhansky’s remark is at the base of my scientific interests. I seek to understand evolution through natural selection at multiple levels, from its molecular mechanisms to a possible epigenetic component. A deep understanding of the relationship between genes, their function, and their evolution, shall give us a better opportunity to explain the delicate interactions between individuals, different species and the environment.
Since life began four billion years ago, organisms were subjected to continuous night day cycles that most probably drove the selection of a molecular clock that allow them to anticipate daily variation in environmental clues. It is possible to recognize a molecular mechanism that generates circadian rhythms of behaviour, metabolism and physiology in all higher organisms and in some prokaryotes. The photoperiodic adaptation of animals that inhabit temperate climate is very interesting from an evolutionary point of view and to monitor climate changes.
I am interested of studying the evolution of the circadian clock and the seasonal timer and cold adaptation in the fruit fly Drosophila melanogaster and in the jewel wasp Nasonia vitripennis.
Gut Microbiota influences flies metabolism, their mating preferences, their fitness strategies.
I am interested in exploring how the gut microbiota participates to flies overwintering strategies and seasonal adaptation.
Flies are model organisms for studying neurogenetics, molecular evolution and behavioural genetics. The combination of these studies can lead to elucidate molecular mechanisms of animal behaviour. Nasonia is a parasitic wasp that has the potential to become the epigenetic molecular model for insect epigenetics.
