Great British Bake Off finalist discusses the parallels between chemistry and baking

Last year on a Friday evening, chemical biology researcher Josh Smalley was in the lab when he received a call inviting him to appear on the 14th and latest season of "The Great British Bake Off." Starting as one of a group of 12 amateur bakers, Smalley made it all the way to the final round, where the top three contestants compete for the winning spot.
