Hi Carol,
Noticed your thread earlier, I actually came across one of these Christian Tortu vases recently, slightly different design to yours, however, same signature to the base. I've attached a photo, just out of interest.
Done a little bit of digging, Christian Tortu, certainly does seem to have a rather mixed background! - Apart from his background mentioned above he does have a few links to the glass world. I did notice that he was actually listed on the Daum France France website under the Artist section:

On a slightly lower key, I did also see one range that he designed was produced by LSA following his design. I gather some of work has been relatively popular, from more of a design point of view than an appreciation of this talents within the world of glass. There are a couple of his glass designs on the following link:

Hope this helps, pic attached of my vase below!
Regards,
Greg
