Research units
The research policy of the EPHE-PSL is supported by a dense network of research units. The faculty members are divided into 48 units. Some are units for which the EPHE-PSL is in charge of; others are units welcoming into their midst professors from the EPHE-PSL. The EPHE-PSL is thus active in 18 units in Humanities and Social Sciences and 30 units in Life and Earth Sciences.
