The on-campus research indirect cost rate at Ohio State is 46% MTDC.
The most difficult faculty arguement that I have encountered
comes from those who claim, "All I use in my research is my
office, my computer and the library."  Of course, they claim that
they get very little value from the "administrative" portion of the
rate.  The paradox is that most of this kind of research tends to be
relatively inexpensive in terms of direct costs and typically funded
by foundations that limit or prohibit indirect costs in the first place,
so I find myself debating with someone who will probably not
encounter the problem
  Best wishes.
