The Sasisekharan Laboratory is part of the HARVARD-MIT HEALTH DIVISION OF HEALTH SCIENCES & TECHNOLOGY (HST) - http://web.mit.edu/tox/sasisekharan/
As well noted in your post, I am sure Ram is more interested in science than money, although money is nice! MIT faculty are the breed of individual that come about money as a result of their intelligence.
