Ellen Phiddian worked in science outreach before deciding to become, in her grandmother's words, "one of those whizz-bang science journalists". With a background in chemistry, she's particularly interested in renewable energy, catalysts, and deciphering the ingredients on food packages. Her favourite podcasts are Wardrobe Crisis,Friends at the Table, and just about any audiodrama. See for privacy information.
