Intra-Specific Variation in Mammalian Social Organisation

Intra-specific variation in social organisation (IVSO) is common but has been ignored in previous comparative studies about social evolution. I will build up a high quality database about social organisation of free ranging mammals, for the first time taking IVSO into account. In phylogenetically controlled analysis I will test for the ancestral form of social organisation in mammals and how taking IVSO into account influences our understanding of social evolution.

Fragmentation of sitting time: new prevention strategy for metabolic health?

Population and experimental studies suggest that reducing and breaking-up sedentary behaviors with frequent, short bouts of activity is a potential strategy to improve metabolic health, especially glycaemic control. However, the long-term effects, underlying mechanisms and influence of individual phenotypes (sex, BMI, glucose tolerance) are unknown. My PhD thesis aims to fill this gap.

How is total energy expenditure is regulated in Humans?

Literature faces currently to a virulent debate according to the fact that physical activity doesn’t increase total energy expenditure, and so might not protect against obesity. However, these studies did not measure accurately each component of total energy expenditure. The aim of my thesis is to manipulate these components in extreme environments to better understand their complex regulation and the role of exercise.
