During my masters degree, I was a teaching assistant for undergraduate course 'X' two times. The professors in charge of the course are titled 'Senior Lecturer' - they are not research faculty.
How would my PhD application look if I had a recommendation letter from one of them?
Bear in mind:
- I have worked extensively with them: meetings, created lecture content, handled student issues, etc.
- I have two other LoR's from research faculty.
- The other options I have (for my third LoR) are: Undergraduate faculty (from a different country) or graduate faculty who's courses I took, but did not interact very significantly.
