I once had the distinct pleasure of hosting the author of BWA (R. Durbin) at Google, and pointing out "That's Mike Burrows, over there, next to Jeff Dean and Sanjay Ghemawat". That led to an interesting discussion between Durbin and Dean on DNA sequence compression. It's not the first time I've been in a room with a bunch of geniuses and simply kept my mouth shut so nobody would know I'm an idiot.
fwiw Heng Li was "the author." He was a postdoc under Durbin's professorship. I was around when bwa was developed and was working in a collaboration with Heng Li (I was working on SOLiD R&D). Any development emails were between Heng and our team, we never spoke with Durbin.

But you're the genius I keep my mouth shut around!
