You are definitely right that the size of their faculty helps with the amount of pubs they get out, thus giving them a high ranking with in most cited polls. Hadn't really thought about this.
I have pretty broad interests, and if I got to Southwestern I may even pursue Biophysics (US News puts Biochem/Biophys in same category, thus still top 10). I don't really know what I want to do. I have talked to all kinds of profs at southwestern, from a natural product chemist, to a RNA biochemist, to a molecular biophysicist, to a quantitative biologist. All but one of these potential advisors is young, but they all have published at least once in either Science, Nature, PNAS, or Cell every year since 2005-2006. On the other hand, my potential advisor at Cambridge (who I have to go to if I go to Cambridge, and she is not from MRC) has only published in PNAS once in 2006. But, she publishes a lot each year (12 in 2008; 19 in 2007). This is a good amount more than my potential advisors at Southwestern.
I guess this is what I need to figure out...
1) I want to work in biotech one day, so how important is that name. YES, a name is important if you want to gain a good faculty position one day, but what about in the biotech world. Usually in business (and I'm guessing in the biotech industry as well), once you get that first job your academic history becomes MUCH less important than your ability to perform in the workplace.
2) Which advisors would be seen as more prestigious; one that publishes a lot in lesser quality journals, or those that publish not as much but in higher quality journals.
Could you maybe tell me a little but about your situation now (school and/or location, field of study, degree pursuing). I am wondering why your profs have never heard of it. Thanks for the responses too.
