I'm lucky enough to get paid to investigate and write about things that interest me. Before I focused on academia, I used to work full-time as a journalist.  At Nature, I was a section editor; at The Economist I initially covered science, then Argentina and Uruguay.

 

   These days I write occasionally on a freelance basis. I pen occasional pieces for Foreign Policy, Nature and The Lancet, and, until recently, also a column for The Guardian's website that fused longevity and wellbeing research (in short, nerdy hints about how to die as late as possible, and until then stay as physically young and happy as possible). I have also edited many a feature and news story for Nature, and managed some of the journal's supplements.

   My writing is loosely grouped under the three headings below, each a kind of science. Health is awkwardly shuffled under natural science.
