Some professors direct large research programs. What is the typical practice for compensating them?
For example, it is not unusual for a top professor to be directing $30 million in research grants every year. If the professor got only 1% of this, it would be a salary of $300,000 per year. I would assume they are paid more than that.
Please do not answer vaguely (impossible to know, it differs from place to place). Obviously, it differs from place to place. I want to know the general and typical practices. What is a common method of compensation.
I am just interested here in compensation for grant-making ability. So, if that is a factor in salary, I would like to know the effect on salary.
