Is he wrong?

I was reading this story on IHT.com about a young-Earth creationist getting a paleontology doctorate. Now, he wrote his doctoral thesis using a conventional geologic model, but there was still debate over whether he should get the degree, seeing as he disagrees with "conventional" paleontology. My question is, "Is he wrong?" - could it be possible that his alternate paradigm (in his terms) is the correct one - his own professors state that he was a good student, obviously knowing enough about geology to merit his degree. Now, could a sharp geology student hold beliefs that contradicted the science he was practising? Does this not suggest that a young-Earth geological model is at least plausible? I'm not saying it can be proved correct, but should it be dismissed out of hand? My bias on the matter is obvious, but I'm going to leave the question open. Peace.
