Welcome back for another episode! This week we chat to Dr Peter Sarkies from Imperial College London / MRC LMS! Peter is a senior lecturer running his own laboratory which aims to make connections between epigenetic gene regulation and evolution. Peter talks to us all about his research involving investigation of a wide range of epigenetic pathways including small RNA's such as Piwi interacting RNAs (piRNAs), DNA methylation and histone modification. Talking about RNAs is a first for us on the podcast, so we really enjoyed listening to everything Peter had to say!  Publication relevant to todays discussion: https://www.nature.com/articles/s41559-020-01293-z?proof=t Blog post relevant to todays discussion: https://lms.mrc.ac.uk/epigenetics-evolution-in-the-fast-lane/ Lab website: https://psarkies.wixsite.com/epievo Contact Peter on twitter here: https://twitter.com/PSarkies
