Assuming it was written by her and not her adviser.
The writing doesn’t sound like the same voice as her advisor’s (e.g. arXiv:1402.1131). OTOH it is plausible that most of the original research in it was the latter’s. Also, the fact that she doesn’t seem to have ever published anything else is pretty suspicious. EDIT: also, she took ten years to finish it.
All in all, I’d guess her IQ is above 100 but below 130.
