and the reason i got interested in that was actually largely from reading about a different field which is prenatal diagnostics where around this time there were uh there was a lot of work being done led by a number of individuals like dennis lowe in hong kong and steve quake who was actually here at stanford in the engineering department basically showing that in pregnant mothers you can detect dna from the fetus in the woman's blood cell free dna again not not inside cells but outside of cells so it's pretty obvious that i mean i was the only person who had this thought that about if we can do that in pregnancy then you know couldn't we try to do the same thing in cancer patients
