<p>For PhD admissions, I've heard the most important factor is LORs and research experience, so I wanted to ask questions about LORs. </p>
<p>First, I'm applying to biomedical engineering PhD programs, however, my mentor and PI in the research group are both Physics PhDs who currently perform bioengineering research, does this matter?</p>
<p>Second, is it recommended to get a LOR from a post-doc? My mentor is a post-doc who completed her PhD in 2006, so she's technically not faculty, but like second-in-command in the research group aside from the PI. </p>
<p>Third, are LORs from the same research group kind of an over-kill? In my research project, both the mentor and the PI will be seeing me in a research setting, but I imagine their LORs would be very similar...so would this be helpful for admissions?</p>
<p>Third, is it ok to get a LOR from a mentor who is not involved in research/academia? I have a mentor in a Non-Profit org who has known me since 2006, and understands my leadership potential, and capablity to create new ideas, would this be beneficial to my application?</p>
<p>Thanks!</p>
