I am an independent plankton scientist based in the UK. My interests lie in how we influence the plankton and its food web through climate change to plastic pollution. I have toured plankton exhibitions in the UK and abroad for science outreach and I created and lead the global, citizen science Secchi Disk phytoplankton study. Why not buy my Ocean Drifters plankton book for you or your child, or watch the Ocean Drifters video to hear David Attenborough describe my secret world, or join the Secchi Disk study if you go to sea.
