As a thank you to my thesis supervisor, I would like to write some sort of letter expressing my gratitude for the work he has done for me.
I was wondering if students ever write letters in such a way that they can be used by professors as a sort of "reference" letter when applying for jobs or teaching grants. For reference, my supervisor is a Senior Lecturer at a university in the Australian system. Would a letter like this be appreciated? What should it look like?
