Thanking supervisor after a year About a year ago, I finished my Master's thesis, which was supervised by one professor from my university, and two people from a different university. One of the two is a professor, but he was not involved much in the daily supervision. When finishing up my thesis and presentation, times were quite hectic, and only now I realised I may have never thanked the professor from the other university as he was not present at my presentation. I did approach him for a reference letter later, and thanked him for that when letting him know I got the job.

Now I feel quite rude, but I am not sure if I should do anything. Mostly, I am afraid of it being awkward if I bring this up after a year. Am I overreacting? What would you recommend?
There are only two possible options here.


Do nothing. Most probably, the professor never realized that you did not thank him for his supervision. He provided what was probably a good reference letter and you already thanked him after getting a job, so I suspect he does not have a bad opinion of you.
Clear up your mind by sending a polite email stating that you just realized you might not have thanked him for his participation in your master project. I do not think this would be awkward. I think any supervisor would be happy to receive such a message. 


Both options are good.
