Dr. Danaé Guiserix

Introduction

I am a postdoctoral researcher working on applying isotope geochemistry to answer questions about modern and past diets.

Short Bio

I am a geochemist with a strong interest in developping isotopic tools to study modern and past diets, with applications in primatology and archaeology. I have completed a Master of Earth Sciences (Research) and a PhD in Geochemistry at the Ecole Normale Supérieure (ENS) in Lyon, France. My PhD thesis focused on developping a method to analyze simultaneously stable (d88Sr) and radiogenic (87Sr/86Sr) strontium isotopes in teeth and bone using MC-ICP-MS. I applied this method, coupled with the analysis of calcium (d44Ca) and zinc (d66Zn) isotopes, to study modern and fossil ecosystems. I especially focused on studying the diet and weaning practices of primates.
