professor
'der Professor' and 'der Wissenschaftler' can both mean people who work at a university or in research. The difference is in the focus: a professor has a specific senior position and an academic title at a university or college. A Wissenschaftler is generally someone who works academically or conducts research. Many professors are also Wissenschaftler, but not every Wissenschaftler is a professor. Learners can easily confuse the words because both often appear in the same environment. If the title or position is important, you say 'Professor'. If the focus is on research, 'Wissenschaftler' fits better.
