I'm lucky enough to have spent many years getting paid to investigate and write about things that interest me. Before I focused on academia, I worked full-time as a journalist. At Nature, I was a section editor; at The Economist I was initially a science correspondent, then the Argentina and Uruguay correspondent.

 

   These days I write only occasionally on a freelance basis. I pen occasional pieces for Foreign Policy, Nature and The Lancet, and, during my PhD, 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.
