The topic was launched by a query over at writedit's blog. Someone wanted to know if any K99/R00 awardees had landed R01 grants.
The answer is yes. Some have.
I suspect the question was motivated by a broader curiosity given that it referred to "success" of the grant program itself.
How would you define "success"?
Do you ask about the proportion that landed R01 support versus folks hired at same time w/o a K99/Roo? Seems to miss the idea that transition to independence was the point of the program. Valid or not, the assumption is that these folks were appointed faculty earlier than otherwise would have been the case. Or, appointed, period.
How about versus postdocs awarded F32 at time of K99s? That seems like a better comparison to me. Or maybe the K01- the K99/R00 population I am familiar with is one that might otherwise have been poised to pursue small level funding in almost-faculty positions typical of K01 recipients of my acquaintance.
On the smaller scale answer about success, I know 4 or 5 current Assistant Profs who were/are K99/R00 recipients. All of them seem to feel this was a positive contribution to their job hunt and negotiations. Although one has R01 support already, I don't think it is necessarily expected value at this point. We'll have to give it another year or two to really assess if they are having trouble landing grants or having an easy time of it, given the difficulties everyone faces right now.
