PhD opportunities at CBI – BEST Doctoral Programme

The CBI (Centre for Integrative Biology) is seeking motivated PhD candidates as part of the BEST Doctoral Programme of the University of Toulouse.

Located in Toulouse, in the sunny southwestern of France, the CBI is a a fundamental biology research institute affiliated with the National Center for Scientific Research (CNRS) – the largest public research organization in France – and the University of Toulouse.

The CBI aims to understand the mechanisms, dynamics and behaviors of living organisms, to advance knowledge on the current societal challenges. Research at the CBI use multidisciplinary and multi-scale approaches, from isolated molecules to whole organisms and animal societies, applied to numerous model organisms, from bacteria to animal models and to humans.
