Recently, I talked with a CS Professor regarding working in his lab as a postdoc. He said that he is interested in my CV/profile, but he can only give me a contract as a teaching staff until he gets the grants next year. However, he said that all the courses he currently instructs are given only in German (which is a constraint for me).
But I was wondering if I'm supposed to do teaching as a postdoc, I shouldn't be expected to act as a TA of his courses. Instead, I should be the instructor of a course and not his own course. At least, that's what I always imagine as the level of teaching responsibilities for a postdoc researcher.
Then, if that assumption is correct, I wonder if I can suggest a few topics that fit his group's research profile and is not given by other groups so that I can instruct in English. For instance as a course (or block course or seminar) in the international track. But, I like to know how realistic/practical this could be before discussing it with him.
