Read excerpt
It’s been a busy month, both in my own life (I landed a new grant! I started teaching!) and elsewhere in my world of science, AI, biology, and academic life. Tomorrow I’m flying down to Mexico City for a week to unplug and recharge. You won’t see much here for a few weeks, but in the meantime, here’s what I’ve been reading this month ¡Nos vemos pronto!Subscribe nowThe AI Discourse in
My relationship with AI is changing (opens the original)
Read excerpt
Personal essay, weekend edition. Starting with a familiar quote often attributed to English economist John Maynard Keynes:1When the facts change, I change my mind. What do you do, sir?I’ve argued here that refusing a useful tool on principle is stubbornness. And after a few weeks of trying to go without AI at all, I still feel that way for the most part
AI + Biosecurity in 4 minutes (opens the original)

I went on CBS19 TV news here in Charlottesville last night to talk about AI and biosecurity. I thought I was walking into a session that was going to be taped and played over a slow news day. I was pleasantly surprised (and a little thrown off) when I found out the segment was live on the evening news! Here’s the recording.

CEPH, CEU, and why Utah reference samples have a French name (opens the original)
Read excerpt
One of the things I love about teaching is that it forces you to confront assumptions and a million little things you don’t fully understand, in case that curious student of yours asks you about it. I’m preparing a lecture for tomorrow morning about various population sequencing projects, from HapMap to 1000 Genomes to ExAC to GnomAD. While preparing to teach the International HapMap Project, I paused for a sec at CEU, a French acronym attached to Utah families from the initial phase of the HapM
