How to evaluate potential advisers on grounds other than their research/publications? While accepting an offer to grad school, one is basically entering into a lasting relationship with one's adviser - most likely, someone whom the applicant has never met before, and the only exposure has been through the potential adviser's website/publications. It is in the interest of both parties to ensure (to the greatest possible extent) that there are no personal/professional traits of either that hamper the formation of a pleasant working relationship - no-one would want to go through the ordeal of having to change advisers midway!

While the faculty has a chance to have a good look at the applicant's profile as well as his motivations (through his grades and SOP), the applicant doesn't have a similar opportunity. So, I'm interested to know what parameters can be used to gauge a potential fit. I've thought of the following:


Past students:

Did anyone ever drop out/change advisers midway, and if so, for what reasons? These would be a bit hard to find though, as I don't expect the faculty concerned would list them on their website. It would be great if anyone could let me know how to find out the list of incoming students to a department for any year.
Publication rate, taking into account the venues where they were accepted.
Time taken to graduate - though I accept this is more dependent on the student, a median figure should be telling ...
What they did post Ph.D. - did anyone get tenure if they went into academia, or is almost everyone unable to break out of being a post-doc?

Tenure status: I'm a bit unsure about this, so wanted the community's opinions about it. Just so that I'm clear, I'm only trying to calibrate the applicant's expectations about the working style of his potential adviser - and hence need to know to what extent are the following "typical" assumptions valid.

Tenured professor

A full professor is more likely to get grant funding, hence less time spent on TAship - but could also mean less time/effort spent on interactions with students (either being busy with other projects/talks, or due to more commitments to family at that age).

Tenure-track faculty (Assistant profs)

More likely to be young and energetic, and could translate to more time spent on one-to-one discussions with grad students - but funding may prove to be an issue, and may have to be on TA for a longer period.


What other factors would be relevant in this matter, and to what extent am I correct/incorrect in either the factors considered, or for undertaking this exercise at all?
There are a few things I would generally look at in a potential advisor beyond just their research/publications:


Who were the co-authors on their papers? Are they actively collaborating with people in your field - people who could be potentially useful for post-doc posts, etc.? Do their students often show up as primary authors on publications, or are they invariably buried in the middle of a long list of authors?
Personality. This goes beyond just do you like the person. Do they prefer frequent updates, meetings and the like, or is the occasional check-in enough? Are they a morning person and you prefer working nights, or the other way around? If you send a long email, would it get answered, or do they not often fail to answer emails? I've had some professors who I'm very fond of nevertheless would make poor advisors because of wildly disparate working styles.
How are their students funded? Your funding stream can have serious impact on your completion time and productivity. If every semester, its a desperate Pick-N-Mix of funded side projects, TAships, etc. you're going to have a lot on your plate that, while potentially an interesting experience, will slow down your progress.
Where do their students end up? Do they have decent career trajectories? Are they supportive of alternative paths like industry or government?
Rank and age. A young professor might be more aggressive and eager, on the other hand they're less established, don't necessarily have the same level of institutional support, and if they're not yet tenured, its possible they'll disappear. An older professor may be more established and stable, but might not use "cutting edge" techniques, or feel less of an internal drive to publish.
