I applied for a prestigious US national laboratory post-doctoral fellowship with a potential mentor. Unfortunately, I got rejected. However, I am very much interested in working in this mentor's group. Note that I am not sure if he is aware of my rejection. I need advice on the following two queries:
- Should I send another email expressing my interest in joining this mentor's group (i.e., on funding acquired by him)? If so, what would be the most polite way to ask him?
- Or should I wait for the next fellowship call and apply then with the same mentor?
