Good grief, blazin, with the way you fire off those questions, has anyone ever told you that you'd have made a terrific auctioneer???
QofQuimica, a few questions about point #1. How would you know their grad record? Is it posted on their website, if they even have one? If not, then from whom would you find out?
Usually, yes. Some profs will even post their CVs on the web, which are full of a wealth of this kind of info. But nearly all profs will at the very least have a short blurb about what they work on, who is in the lab, and some of their pubs. It's always a good idea to google the profs before you go meet with them.
Also, when you says pubs, how many is a good amount and how recent should they be?
This is going to be highly field-dependent. I did my PhD in organic chemistry, so I'm not going to even try to tell you how many pubs a cell bio lab or whatever other bio field you're likely thinking about should be putting out.
Also how would you know and from whom would you find out if they give credit for work done by their students-- from the other grads working in the lab?
Look at their pubs. If the PI puts himself as first author all the time, that's a bad sign. If the PI writes a lot of articles by himself with no co-authors (not talking about reviews), that's a bad sign.
Also do you assess a PI's skills based on the # of pubs and the journals in whcih they published?
Not sure what you mean by this. What kind of skills?
Also how do you know how well funded the lab is?
If you're lucky enough to get hold of a CV, it will have this info. Otherwise, you're going to have to ask people.
I would first look at the lab's website, which is almost always out of date. This is great, because the members listed have probably moved on, and can give an honest opinion of their experience. E-mail them or call them. Plus, papers take so long to publish that it is more accurate to look at past member's publishing record. I then just look their names up on pubmed and look at 1) their authorship and 2) the rate of publishing (at least 1 every 2 years is good, feel free to disagree on that) .
I generally agree, with the caveat that it depends on the field and the size of the lab for your second point. For example, organic chemists tend to not be as prolific as computational or analytical chemists. I knew people in grad school who finished their PhDs in analytical with half a dozen papers *already published* and more submitted. I can darn well guarantee you that this would be a rare and extremely fortuitous situation to find yourself in as a newly minted organic chem PhD. Theoretical folks totally have it made compared to experimentalists.
