I'm currently an undergrad who has been working at this lab for 1 year. In the beginning, I was pretty slow with research and I still make mistakes sometimes. For instance, it took me 4 months to get a western to properly work and 1 month to properly clone something. I'm not as bright as the other interns, but I learned a lot this 1 year about techniques and scientific knowledge. Granted, I don't know if I'm 'competent' enough for research.
Anyways, my research mentor (post-doc) left for a new position, and now I'm pretty much without a mentor. I emailed my PI for a new mentor assignment if possible a week ago, no response. My former mentor emails my PI and gets no response. Now, I decide to follow-up with him yesterday - still no response. So in total, 3 emails (2 from me, 1 from my former mentor) sent to my PI about this topic in the last week.
I'm not the closest to my PI. He seems always busy and I haven't spoken to him very often. However, it's unlike him to take a very long time to respond to emails, as he usually responds within 1-2 days.
Does this mean I've been ghosted by my PI/given a boot from lab? My former mentor told me that my PI would be willing to let me continue working, but I don't know if he was just saying that.
I'm not sure if I should reach out to other post-docs/grad-students in the lab and ask them if they can be my new supervisor mentor. So far, I haven't had much work to do so I've been staying back home and reading papers the lab has published/to see if any of interest. The other people in the lab familiar with my name; I hope they're not thinking about how stupid I am since I did make lots of dumb mistakes. I know the lab manager doesn't like me that much (one time I was giving a lab presentation and she was shaking her head), and usually she's the de facto person people turn for conflicts such as these.
What should I do? I've been in a state of rumination about this for a long, long time. I'm really interested in the work of this lab.
