So I've been working with one professor for about two years in a condensed matter lab. As I think about getting LOR writers for next year, I'm in a bit of trouble since I've only really done research with one professor in the physics department.
Other potential LOR writers:
1) two supervising professors for my philosophy senior thesis on ethics in science
2) two supervising professors for history of science classes that I TA'd for
3) graduate students in my lab
4) professors who I didn't really interact with but got A's in their physics classes
I was wondering, would any of these be good options for LORs? Or should I really try to get more research done under another professor?
Thanks for reading this!
