Atul Butte died yesterday. The world lost a giant. A big bear of a man. With a huge smile. With love for everyone. With energy that could power a room. I loved everything about Atul. I loved how he was always happy. I loved how excited he was about science and helping people.

The Big Five personality traits definitely have clear genetic determinants. I'm surprised by the lack of spousal assortment and lack of shared environmental confounding though...Anyone care to guess why this is the case? www.biorxiv.org/content/10.1...

Bit of a standard moan - “epigenetic association studies” are *very* hypothesis / model different vs GWAS (genotype association studies) even though the process v similar (put DNA on arrays, call alleles/epi-alleles, do association with covariates). *completely* different
