"If you zoom in on the boundary of human knowledge in the direction of genetics, there's something just outside humanity's reach. My wife and I chose to start funding these graduate students after we learned that our son has a rare, fatal genetic disorder. It may be too late for my son, but it's not too late for other children. Even one child suffering is one child too many. The only way to end this kind of suffering is science. And, the best way to do science is through graduate students."
