I've been asked to do another NSF review panel this spring. Given that I did one in the fall of 2010, a second one pre-tenure might be a little excessive. However, with the new submission policies in BIO, I am tempted. I would be reviewing preproposals, which might provide some insight into the new process. Also, there is no commitment to reviewing the full proposals in the fall*, so it would only be a spring commitment.
Good idea or bad?
*BTW, I think this is a huge miss on NSF's part. Why change the reviewers between when the bar is set and when the money is decided? I can't understand the logic here.
