<p>So I need a bit of advice on who should write my 3 letters of recommendation for graduate school (Chemistry PhD).
I am certain that 2 professors from my University (both of whom have advised me while working in their labs as an undergrad) will write the first two.
I have several options for my third (summer internship research advisors), and I'm not sure the best route to go...</p>
<p>-Scientist (PI) at a Biotech/bioscience company (I'm not giving the name, but it is someplace along the lines of Biogen Idec, Millipore, BD Biosciences, etc). I still keep in touch with her and probably know her the best of the three. Also, I am an author on a paper that she wrote involving my work there.<br>
-Scientist (PI) at a large pharma. company (Again, not giving the name, but it's comparable to someplace like Novartis, Bayer, GSK, etc). Less communication with him, but probably a better known company. No paper.
-Professor (PI) at a well-known German University. I received a scholarship to come to the University and work last summer. Probably no paper (at least before my grad. apps are due...). Didn't have too much contact with the professor (it was a large group) as I spent most of my time working under a grad student/post-doc.</p>
