About the author

I’m a post-doc working at NASA Jet Propulsion Laboratory on deep-sea hydrothermal vents systems. I use stable isotope methods to disentangle the food web, and trace carbon, nitrogen and sulphur pathways, around hydrothermal vents at the Mid-Cayman Rise. My broader interests range from biomineralisation to palaeoclimatology and archaeology. I write my own blog at http://silentwitnesss.wordpress.com/ and occasionally tweet as @emmaversteegh.
