I think she'll do great at Cornell. She'll be a chairwoman in the future no doubt.
She does run a tight ship. I do, however, have some criticisms. She didn't make herself known too well to the residents. Her PD letters for fellowship would echo this with generalized statements. In large part this didn't harm our residents, as we have great fellowship placement, and I don't expect it to be a problem for Cornell. I would have liked to see her face around more, with engaging conversations at all levels.
I think she was partly to blame as to why our FMG percentage kept rising year after year (now to just over 50%). When I interviewed in the midwest, programs would hand write notes or send letter correspondence and really make you feel wanted. This did not happen to any great extent. So, I really felt like we lost out on talented midwestern candidates because she came across as stern, distanced. This is not who she really is, but how she came across. She is really a great PD, but didn't take the time to massage the finer aspects of recruitment season. This is obviously not a concern for Cornell, because it's name will recruit for itself.
On paper (academic credentials, networking, etc) she is top notch. I think the finer aspects are what make or break mid to high tier midwestern IM programs, who need vibrant, caring, outgoing PD's (in my opinion).
All in all, I think she will flourish at Cornell. She was trained in an East Coast setting and will do well back in her "zone".
