I would like to know if PhD advisors allow students to collaborate with professors from other institutions in a major way. The context for me here is that I will be joining a Top-50 institution for a PhD in Physics. Considering the job prospects in academia, I think it would be worth collaborating with the topmost people in the field directly (who generally reside at topmost universities like Stanford, MIT, Princeton, etc.) to get solid recommendations from them along with my advisor's recommendation (assuming I produce good quality research with them). I would like to know how such an arrangement can be made possible without making my advisor feel bad. Are such arrangements common?

Of course, my current institution has brilliant professors as well and I would like to do my best to produce good research with them too. This is why the consent of my advisor in whatever I do is very important to me. I just want to make things as productive as possible in my current PhD program and have the best people in the field write recommendations for me so that I could continue working in academia.

If two faculty members are interested in collaborating with one another, an excellent way to bootstrap such a collaboration is with a strong student who is interested in being working with both. This is often much easier than the faculty members trying to work directly with one another, since they are often each quite busy. It also often ends up resulting in a co-advising arrangement, either formally or just de facto. With the right student and project, this can be a really good, productive, and career-positive experience for everybody involved (it certainly has been for me as the external co-advisor), and many faculty members that I know tend to welcome such opportunities.

If you want to build an independent collaboration that does not involve your advisor, on the other hand, you should not be surprised if you run into resistance, particularly if your advisor is funding your position.

    Thanks for your response. I definitely do not want to do things keeping my advisor in dark. It would be good for me that I get to work with the topmost people in the field with my advisor in the loop as well somehow. Jun 19, 2015 at 8:17

Interesting thought. I will try to offer some factors to consider related to the approach you are suggesting.

  1. There's a risk of spreading yourself too thin. All things held constant, I would expect it to be more difficult on average to build relationships with faculty at institutions other than your PhD "home base." The time and effort spent building these relationships would thus be re-routed from what should be your main thrust, i.e. developing a reputation as an excellent student in a place that actually voted to have you and invested resources in you.

  2. Faculty at top institutions are extremely busy and inundated with queries from all sorts of places and people who want their time and attention on collaborations of various types. Successful faculty are very strategic about where they invest their energies (especially in Physics? sorry, bad pun). This partly explains the uphill battle presumed in point #1. They usually have plenty of students and postdocs of their own who want to "collaborate." The returns from such one-off partnerships with this or that individual who met them at this or that conference are dubious, and typically high-flying faculty end up collaborating on high-visibility/payoff projects. Unless your work will fall in that category, I think productive sustained collaboration with quality attention and care invested in the relationship on both sides is highly unlikely.

  3. The only relatively common, accepted form of collaboration with faculty from other institutions that I am aware of is IF those individuals are members of your dissertation committee. Colleges (at least in the U.S.) often require that at least one committee member be from another department at the home institution. Along the same lines, it is typically viewed as OK if there is another, additional committee member from another institution, as long as their being on the committee is well justified, e.g. by filling a gap in expertise or being in a unique position to contribute something given their specific context/resources. In contrast, collaboration on side projects can cause some minor (which could become major if left unchecked) issues involving your Advisor wondering what the heck is taking up your time that you could be spending in his lab and writing his papers...

This being said, it is possible that in some disciplines such collaborations are more frequent and more accepted than in others, and may pay off in some ways. However, the though I would like to leave you with is to carefully reflect whether such collaboration will in fact help your career plans, over and above similar collaborations with faculty at your home institution. If you find yourself in a situation/project where the answer is a clear YES, well, you can at least give it a shot and see what happens.

However, if by looking over the fence (where the grass typically looks greener) you might end up missing some gems on your own lawn, I would say stick to the familiar environment and try to make the most of the opportunities under your nose.

Lastly, collaboration can take many forms. It may not be necessary to go it alone and try to carve out an independent project with someone from another university/lab. Being on a research team (as a Research Assistant) that has some external partnerships with teams at other institutions can be enough to develop some contacts and build some name recognition in those places. Being considered a valuable member of the research team at home, and being valued by your own Advisor can speak louder than trying to convince someone on the outside that you are wonderful and totally worth their attention. When you will be close to graduating, if your Advisor believes in your potential, s/he will go a long way to help you network with various other labs/teams that s/he has relationships with. I personally would recommend this more "organic" route.

The academe is a big boat that doesn't like to be rocked, and stability is generally considered an asset. Having a reputation for dedication to one or two large-scale, complex, team projects is probably going to help you more than having 10 separate fledgling solo projects/partnerships. (Note: If you were an undergrad with a major in Business/Entrepreneurship, this advice would be the opposite. But a PhD in Physics seems more aligned with the solid/long-term academic paradigm.) Whichever way you choose to play your cards, good luck!

    Why is this so negative? "The only relatively common, accepted form of collaboration with faculty from other institutions that I am aware of is IF those individuals are members of your dissertation committee." Well, I'm on my way to spend a week collaborating with someone not on my committee. I've done this numerous times, and it's always been very productive...

    "I would expect it to be more difficult on average to build relationships with faculty at institutions" Perhaps, but it's common wisdom in my field (astrophysics) that not having any letters of recommendation from outside one's home institution is a very bad sign for postdoc opportunities.

  • @ChrisWhite, thank you for the counterpoints, this provides a better overall perspective. I guess I was speaking from personal experience and what I observed among my peers (in the social sciences) where outside collaborations weren't a major factor in employment prospects.

Yes. I recommend it and endorse the strategy.

I was a PhD student in the UK, but I think in total I spent more time working in Japan, France and California than I did at my institution in the United Kingdom.

At the beginning, all trips were at my advisor's suggestion (he was very well connected in numerous collaborations himself) but as time went on I built up my own "network", and eventually it became normal that I would be "invited" to join in directly.

As you can imagine I left my PhD with a lot of air miles, and more importantly I knew a lot of people on whom I could count for a good reference.

However it was never a "co-advising" situation as some have described. I always felt that I was visiting as my advisor's representative, and I always tried to keep it that way. As with any job it is important to manage your relationships with people carefully; if it seems like you are suggesting making your advisor redundant she is probably not going to be happy about the idea. Therefore I would always be sure to talk regularly with my advisor when I was in town and to keep him in the loop by email or phone if I was away.

  • A very important point is that of managing interpersonal relationships. A.k.a. "being fair". Jun 19, 2015 at 0:02
  • @paulgarret Can you expand on what you mean by "being fair"?

    Well, I guess "being fair" includes not swindling people. Not taking anything from the under false pretenses. Not giving away their confidential/secret information, that they might feel gives them a useful edge. As though one signed a "non-disclosure agreement" with nearly everyone one spoke to, especially one's advisor. Violation of expected confidentiality will not only upset people but will trash one's reputation. Is this responding to your query? Jun 19, 2015 at 0:36
  • @paulgarrett I see what you are saying about misusing other people's work. However, I always worked in very collaborative atmospheres where we were all strongly encouraged to share our ideas (with attribution) rather than guard them as secrets.

    Very good that you've had positive experiences! But we note that not everyone plays fair. Attribution/acknowledgement is, in my opinion, perhaps the most critical human-aspect thing about any progress. Both acknowledging "prior art", and explaining how one "came this way". :) Jun 19, 2015 at 0:43

As a supplement to the other good answers, one might be a bit careful, since one model of "PhD advising" is for the advisor to give a student a sort of "insider information" (much like the notion of "insider trading" on the stock market, which is illegal... unless you're a member of Congress, but nevermind...), which the advisor might want to keep "inside". And the student should, hopefully, benefit from having this sort of head-start, as opposed to competing against more experienced people in real time.

Especially if the advisor has more than one student, keeping information (temporarily) non-public benefits all of them, so any one of them "blabbing" dis-serves the others, which is a bad thing. Vaguely reminiscent of the game-theoretic aspects of "prisoners' dilemma".
