I'm curious, what is it that you might happen as a result of having a creationist biologist, who has proven his knowledge and understanding of biology beyond a doubt, doing research? And don't say if they believe in evolution, they don't understand biology. I'm talking about understanding biochemistry, the various mechanisms by which organisms function and reproduce, DNA, etc.
In addition, merely mentioning 'alternatives to evolution' in a grant proposal in a biological field would be the certain kiss of death. It's like mentioning Area 51 or contrails or alien abductions. Tinfoil helmet stuff. One thing academic departments won't do these days is hire unfundable faculty. And if the candidate meantioned his creationism to a search committee, why wouldn't he be foolhardy enough to mention it to a granting agency?
Science is not subject to the first amendment. We dismiss damnfool ideas out of hand every day. Evolution, in the minds of 99+% of working biologists, occupies so central a position in biology that anything questioning its fundamental truth (as opposed to the details of its mechanism) qualifies as a damnfool idea.
