I had a telephone conversation with a proposed Ph.D. supervisor last Monday and he agreed that he will double-check my research proposal before I submit it. Then I emailed him the proposal. However, I haven't heard from him for a week, so I sent a reminder email to him this Monday. And yet still no feedback from him so far. I know that professors are busy and slow responders, but Christmas is coming and I do not want to miss the deadline. I wonder whether it is ok for me to call him at the same time as last time if I do not get his response before next Monday? Or are there any other solutions in this situation?

    Why don't you call or email his assistant first? He could be traveling. Or, maybe he doesn't check/use email (yes, that happens, even in Computer Science).

  • @cabad Unfortunately, he has no assistant.

    Personally, I both find phone calls these days intrusive and unpleasant, and ignore those from numbers I don't recognize for sure. So I would consider this unpleasantly pushy...but that is only how I feel of course. For safety, I'd rather sent a brief follow up mail with a crisp, friendly, good title short enough to get the gist of your mail w/o even opening it. Nov 19, 2014 at 16:48

    If he does not care about your PhD proposal and about your emails, maybe he is not the right advisor for you... Nov 19, 2014 at 16:52

First, ask yourself whether you are sending the right email.

One of my professor mentors had a very useful heuristic for ensuring effective communication with busy people. For any busy person, email typically gets triaged into three bins:

  1. Email that can be safely ignored.
  2. Email that can be responded to with trivial effort, thereby clearing it from their "todo list."
  3. Email that requires non-trivial effort to respond, and must be put off for later... and later may be a long time, because now it's competing with their other "large" duties.

If you want a response from a busy person, write a short email that includes precisely one question, and make sure that question is easy to respond to. For example, in your case, if you send email saying:

Here is my research proposal, as discussed. Can you please send me feedback?

then that might get no response until the professor has the feedback ready, and preparing your feedback may get pushed off and pushed off again. The professor might also misremember the deadline and have a lesser sense of urgency. If instead you write:

Here is my research proposal, as discussed. Please recall that I must submit before the deadline of XXX, and I would like time to revise if necessary. When can I expect your feedback?

In this you've posed an easy question, which should get a response, and also gotten them to commit to a specific date. If you don't get a response in a day or two from an "easy" email like this, then you need to wonder whether this person is actually somebody you want to work with.

What, however, if you send the right email, get them to commit to a date, and then they fail to either respond or tell you they need more time? At that point, I would recommend against either emailing or calling on the phone. Instead, go find the professor in person. I have found that with busy people who fail on their commitments, that finding them in person is the best way to get yourself back in their queue. Again, however, you should ask yourself whether you really want your whole Ph.D. to be this way, because it is likely to be a pattern...


If you are danger of missing a deadline, yes call her/him. @jakebeal's answer is great for email, but sometimes people just don't check their email.

If you are worried about seeming too "pushy" or aggressive, just be really polite and give a sense that you are trying to get things done and moving, rather than blaming her/him for the delay.
