There may be individual academics/sociologists at universities with interest, but finding them would be very challenging. IMO, reaching out to (French) academic societies, publishers, associations etc. could be more fruitful.
I did make a sale to Emory University years ago, and have sold names to State Governments (sold PureMichigan dot com) but that was a lot of work. Takes a lot of work and ingenuity and not having big expectations. Good luck in whatever path you take!
