Till att börja med, Jag är utbildad som läkare och psykiater. Jag gick igenom psykoanalys personligen.

Min avhandling för examen i psykiatri – ett krav för denna grad i Frankrike – var att bygga och skapa en expert system som integrerar alla DSM III regler (Diagnostisk och statistisk Manual över mentala störningar — American Psychiatric Association).

Till 1979, I worked in many psychiatric institutions and hospitals. Then I decided to leave them to start a private practice as psychoanalyst, psychotherapist, and psychiatrist. A practice I still have today.

Since I had been trained as an engineer in computer science and electronics at the time I was studying medicine, I decided to work in the world of industrial engineering. From 1980 to 1986 I was involved in Artificial Intelligence projects.

Meanwhile for my personal researches I was building a system able to automatically analyse a corpus of Jacques Lacan’s quotations. The system can be understood as a system for syntactic and semantics analysis. It had been named Sinfrasis.

Then I started a company called Symphrasis specialized in speech processing and natural language processing in 1987 with a friend. The company lasted till 1994. In this context I met Ron Brachman from AT&T Bell in NJ. Through him I had access to very interesting Knowledge Representation systems dedicated to building intelligent complex taxonomies, Kl-one, Klassisk, Loom.

Sedan 1995, I have been working in psychiatric institutions for abused children, drug addicts, deaf children, teenagers with major speech disorders

Presently my major research focus is automatic language processing systems, topology, and logic.

By applying these techniques to Jacques Lacan teachings, I write papers on the topological approach to the subject of the unconscious, and I have published two books that are thesaurus of thousands of quotations made by Lacan. They are presented as a kind of paper hypertext where quotations can be accessed through each of the various concepts involved.

• Les phrases clefs de Jacques Lacan 1953-1957
