Présentation

Main research interest 

I am a demographer with broad interests in understanding the biological, environmental, cultural and social determinants of demographic traits (as fertility and survival) in humans. 

Questions that particularly interest me include (i) how and why such traits vary over time and between populations, (ii) how these demographic traits influence (and are influenced by) population dynamics, and (iii) how they have evolved during human history. My main research focuses are currently on two aspects:

 

  • The investigation of the joint evolution of life-history and sociality (in the ecological sense) in our species.

  • To study of the evolution of senescence in our species : Why do we age ? At what pace ? Do all functional systems age at the same pace ? What are the social drivers of - and the constraints on - senescence ?
