Andry, this conference draws in as you say thousands of researchers who all have their results to share. How do you cut through the noise and work out which if any are going to be the real game changes? Yeah, it is very difficult because there is so much research being presented but also I'd point out that this particular conference has a really high sort of bar when it comes to abstracts and discussions that are presented there. It almost makes your job a bit harder though because if there's research there which is clearly bad, it's quite easy to put to one side.
