Following medical studies, Nathan obtained a Ph.D. at the Ecole Normale Supérieure in Paris, and worked as a postdoc at the California Institute of Technology and the Swiss Federal Institute of Technology.

After two years at the Centre d’Economie de la Sorbonne in Paris, he is now a CNRS research director at the Laboratoire de Psychologie & Neurocognition in Grenoble.

Between 2019 and 2024, his research was dedicated to metAction, an ERC-funded project which aims to document the contribution of sensorimotor signals to metacognition, and develop new remediation procedures.

He is now focusing on a new ERC-funded project named volta, aiming at identifying electrophysiological and electrochemical correlates of auditory consciousness in awake, asleep, and anesthetized individuals with epilepsy implanted with micro-electrodes.
