Finding an advisor can be a lot of work.
Here is what the graduate council has to say about the advisee/advisor relationship: Mentoring Guidelines
In the process of finding this person, it can help to reflect upon what you hope or think the grad school experience should entail, and gauge potential advisors using these things as a guide. This document will talk about finding an advisor in the context of the following ideas:
This last item is a bit tongue-in-cheek, but it is true that grad school can be very trying at times (but not all the time!). It is important to reduce any sources of anxiety that you can -- stress is an unavoidable part of life sometimes; and it is equally important to increase your productivity/overall content as a grad student in any way that you can.
Once you find some areas that you are interested in, you may want to find an advisor who knows something about at least one of those areas. To get to know the faculty, you can:
By the way, if a faculty member proposes a project that you try and then don't find interesting, it's okay to tell them. There's a true story of a professor at the University of Oklahoma who turned down four projects from his advisor, until finally the advisor said, "I think you actually want to work with (this other person). " This other person turned out to be a much better match for him, and he ended up being very excited about, and therefore motivated by, his final dissertation project.
When considering a faculty member as a potential advisor, find out:
This last criterion is only one indicator, and not necessarily the most important one. There is a true story of a grad student in Davis (not in math) who was choosing between two professors as an advisor. Both were interesting researchers, but the one who seemed nicer and more accessible had never had students before; whereas the other one had been tenured for years and had many students and was an excellent lecturer. This grad student was advised to choose the senior professor by many people, and did. Unfortunately, as excellent of a lecturer as this senior professor was, he was terrible one-on-one, never made time for his students, and didn't care when the grad student told him her results. When the grad student tried to switch labs, he wouldn't let her. Through all this, the junior professor continued to answer questions from the grad student, and helped her with her labwork. The grad student wished that she had talked to other students about what was was really like working at the senior professor's lab before agreeing to be his student. (Disclaimer: there are plenty of tenured professors who are friendly! This story was just included to illustrate the importance of finding out as much as you can about an advisor before signing on.)
If you want a job outside of academia, you might ask around to see if the faculty member has landed students such jobs/is supportive of students finding jobs outside academia.
Your advisor should serve as your advocate to the department. If you are ever caught in a situation where it becomes necessary for someone to stand up for you -- for example, TA issues, department political issues -- your advisor should be someone who can do that.
Finally, every advisor has a different working style with their students. For example, some advisors meet with their students every week; others once a month; others once every two months. What is the style that suits you best? Some advisors like to give their students projects and reading; other advisors would rather have students find their own projects, and make a point of not suggesting problems early on. Some advisors prefer their students to work independently, others will expect their students to collaborate. When considering advisor choices, keep the following in mind:
Remember that your advisor is human too, and moreover that they have duties other than being your advisor: classes to teach, other students to advise, committees to serve on, committees to chair, perhaps a family to parent. Just because they don't answer your emails, or seem a little out-of-it or moody during a meeting doesn't mean they've suddenly decided you aren't worth their time. It may mean that they have lots of stuff to think about. Your relationship with your advisor, just like your relationship with many other people, isn't a life-or-death situation -- you are both human. On the same token, if you haven't been able to see them for a long time, and they haven't answered your emails, it may be worth finding out why (instead of imagining grand hypotheses on why you are a bad student...) and seeing if other students are experiencing the same thing.
It is okay, and even encouraged, to seek out other faculty members! Sometimes your advisor is the best person to talk to. Sometimes your advisor isn't. A former student once said that she liked to talk to a particular set of four professors: "one for the weird explanation", "one for the standard explanation", "one for the quick explanation", and "one for the clear explanation." The first one described her advisor.
Some advisors will assign reading and ask their students to present a coherent summary of it to them when they meet; others might be surprised if you try this. (If this is something that you know you will benefit from, you should go ahead and do it, and then they won't be surprised the next time.) Some advisors will quiz you on that reading.
Some advisors won't assign reading, and expect you to find reading material for yourself. You could choose to summarize what you've read to them, or tell them what you are reading and ask for related references and problems.
If you've written some sort of program or think you've proven something, you should let your advisor know.
Here are some things that were taken from the UC Davis Graduate Council Mentoring Guidelines (a great document!)
As partners in the mentoring relationship, graduate students have responsibilities. As mentees, students should:
