No clue, I don't know her personally. But speculating from what she writes about on her website regarding her interest in teaching, I would assume she is interested in a faculty position at some point in the future.

I really can't blame her for the self-promotion. I think this in some ways is the academic equivalent of the acquisition: she got the scoop on a really novel idea, she's well positioned to do future work in the area and be recognized as the global expert (catch the "more to come in the next 15-30 years!" in the press conference), and she's really excited about the work. I can only assume biogeochemistry is not having loads of money thrown at it these days so she's smart to take advantage of this opportunity to really make a name for herself.
