Nessa Carey is a British molecular biologist and science writer. She earned her PhD in the United Kingdom and worked as a researcher in academia before moving into the biotechnology and pharmaceutical industries, where she led research and drug discovery work. She later became a Visiting Professor at Imperial College London and has worked as a consultant and lecturer. Her main subject is epigenetics, the study of how genes are switched on and off without changes to the DNA sequence. Her books for general readers include The Epigenetics Revolution (2012), Junk DNA (2015) and Hacking the Code of Life (2019). They explain laboratory experiments and medical findings in plain language, using analogies and case studies. Her work helped bring epigenetics to a wide audience at a time when the field was moving from specialist journals into public discussion.
