After a dozen years working in cognitive sciences on linkages between artificial intelligence, cognitive psychology, linguistics and the sociology of groups, since the decade of the 2000s my work has evolved towards issues in sociology, epidemiology and the epistemology of health, especially of mental health.

At present, I am interested in mental disorders and more specifically in depression, suicide and obsessive-compulsive disorders, in psychotherapies, and in mental health prevention programmes. In particular, I am developing a sociologically and epistemologically informed critical analysis of methods and paradigms for evaluating the effectiveness of health care actions, particularly in the context of extending the logic of Evidence-Based Medicine (EBM) to medicine in mental health (EBMM), and in light of the developing interest of public health workers for mental health. More broadly, my work is part of an approach to the epistemological and sociological elucidation of “measurement” in mental health, and the social practices it leads to.

In this context, for several years I have been developing a theoretical, empirical and applied research programme on the present and potential uses of digital technology and related subjects in mental health and psychiatry (“e-health”).
