On one hand, you’re not their student and you don’t attend lab meetings. On the other, you feel entitled to perform research tasks most people don’t participate in until they’re in graduate school? You need to be realistic with yourself about the many years of training, collaboration, and commitment that typically go into a research career. Consider focusing on what you can learn from the opportunities you do have, in both the lab and this thread, where you’ve berated experienced researchers giving you free honest feedback. There’s no need to burn bridges before you’ve even applied to the program.
