Franck GUY

CNRS Researcher

Main research question

My research focus on hominin origin and evolution. In particular, I’m interested in cranial and dental material of African Mio-Pliocene hominins.

Topics of study

Among various approaches, I notably use tools and methods derived from the field of 3D imaging (µCT-scan, 3D virtual data analysis 3D eg morphometry), an efficient way to finely characterize morphology and its variation.

In addition, I develop a project based on 3D topographic analyses which aims to study dental adaptation and evolution in primates (in collaboration with V. Lazzari).


The field work comprises regular or occasional field missions in Ethiopia (coll. JR Boisserie), Greece (coll. G. Merceron), Morocco (coll. M. Benammi) or Romania (coll. G. Daver). My principal field activity takes place in Chad with numerous filed missions carried out from 1996 to 2008 (coll. M. Brunet) and coming new field campaigns.

Project management

I contribute to various projects, notably the ANRs OLD (PIs A. Delagnes & JR Boisserie) and Diet-Scratches (PI G. Merceron). I initiated the ANR project DieT-PrimE (2018-2021) in collaboration with V. Lazzari.

Other responsibilities
