According to a few sources Dini is a Christian and according to The NY Times, a devout Catholic. The debate should be over. But Mark Kleiman still chooses politics over science.
The question over whether creationism limits one's ability to conduct science is tricky. It would have to be taken on a case by case basis, and would require an examintion in itself. A comment on Electrolite says drug-resistant bacteria do not challenge a creationist viewpoint. Is this true? I don't know. What I do know is that many people, and even some lawyers including Eugene Volokh, do not even understand the point of the question. Kleiman himself says "Medicine is not a science' preferring to see it, in it's need for social interaction, as a 'Profession.' Actually, for a good doctor, it is both.
Perhaps this confusion comes about because lawyers may make use of a casuistic logic- indeed are required to- while biologists do not have that luxury. Dini therefore limits such indulgences to his private life and asks his students to do likewise.
The issue seems pretty clear, but I will admit to a Kleiman-like appreciation of fact that Dini takes his religion seriously. It takes some of the pressure off. But then again, I never said there wasn't any, only that it shouldn't come from 'us'; or more sensibly, that we should judge it all carefully before deciding.

That's it for now. It's Monday and again, I'm tired and dusty. The job is coming along well. Next up I think we're ripping up the kitchen floor and pouring a slab with a 'radiant heat' system. One of the guys on the job know is a graduate of an East German trade school. Some interesting conversations.
tschüs!
