I saw this and couldn't hold my tongue. I'm a recent grad from UTSW (within the last 3 years). Re: Dr. Cavanagh:
1) the man is brilliant. extremely smart, knows tons of basic science, and is a great teacher. he really knows corneal/anterior segment disease on a deep level and is happy to teach.
2) you rarely see him. as a second year, you spend one morning a week in clinic with him for 6 weeks. otherwise, you only see him if he lectures to you (maybe 1-2x a year) or is at a departmental conference (once every month or two). it's easy to forget he is part of the program unless you seek out contact with him.
tbh, I avoided reading that book because I wasn't sure what I would do with the information. He doesn't operate, and he doesn't take any new patients -- I think his main role is research (he's been writing grants for years) and administrative stuff. But I'm not sure what he actually does as vice-chair...I hardly interacted with him as I didn't apply cornea. It wasn't an issue for my fellowship applications -- I went where I wanted to go. If I was interested in cornea? Who knows if I would have gotten his rec letter -- I'm sure it could have been polarizing. But on the rare occasion that you do talk to him, it's a positive learning experience. For 99% of the residency experience, it's a complete non-issue...
