I am a PhD student in Applied Mathematics. I submitted my Phd thesis and starting to apply for postdoc positions.
In my PhD thesis I have one work published in a tier 1 math journal and the other two works still unpublished. My question is the following: Should I submit the unpublished works in tier 1 journals and try to improve the quality of the manuscripts (with the reviewer's suggestions) or, submit to 2nd/3rd tier journals so that it gets accepted as soon as possible so that my paper count increases. I want to apply for faculty positions after 2 years from now. At this phase of my career what option should I choose?
