Academic dismissal from PhD program. What next? A couple semesters after beginning my PhD program (in the US), I was dismissed from the program because:


My GPA was slightly below the program's minimum (after being on academic probation for one semester already).
After months of work as an RA in a research group, at the end of the semester, my adviser informed me that he was not satisfied with my research and would not continue to fund me.
After that, the department was not willing to hire me as a TA, because TA funding was seen as an "interim" measure, and having a new adviser was necessary to continue in the program.
I couldn't find a new research adviser because everybody would freak out about my GPA.


However, I have done very well on exams, and I had a great GRE score. What are my options now? Applying again? What could I say about my messed up situation in applications? What if I applied to another school?
This answer is going to sting, but it's how I read the situation based on what you've written here. It sounds like there is something going on that you haven't addressed.

If a department wanted to keep someone who they felt was a promising student, who they thought could contribute with good work, I think they'd find a way to waive the GPA for another term, seeing that it's so close to the threshold. On the other hand, if they felt like a student was not worth keeping, they might be relieved that the student's GPA fell below the specified threshold, so they could use it as grounds for dismissal from the program.

As for the lab reports, there's a difference between being late and being unreliable. One is a fact, and the other is a perception. You emphasize the fact, but I suspect it's the perception that is behind their unwillingness to rehire.

As for the GRE score, those scores used to measure potential from an admissions perspective. Once you're in the program, GRE scores become pretty much meaningless; from that point on, you're judged by the work you do at the institution. (The fact that you even mention it makes me wonder if you have a habit of overestimating your own value in a way that annoys your professors and your peers.)

As for your options, I wouldn't recommend reapplying. That's an uphill battle; they seem to be sending pretty clear signals that they'd rather be done with you. That leaves transferring somewhere else. Given that your GPA is so close to 3.0, I'll bet you could find a school willing to accept you as a transfer student; however, they might have second thoughts based on some of the reasons for your departure. I would be very careful about who I listed as a reference from the school that is dismissing you now. 

You might want to look in the mirror, and try to more accurately assess why you are being let go. As I mentioned, I think it has to do with intangible qualities such as personality, reliability, and teamwork – things that are hard to quantify, but easy to spot notice once you start working alongside someone, especially in an environment where the goal is to achieve a complex and long-term endeavor.
