The Howe Group works on several topics to do with photosynthetic organisms and their relatives. Projects include how photosynthetic organisms protect themselves against stressful light levels – absorbing light energy is important for photosynthesis, but is dangerous in excess! We are also interested in the exploitation of photosynthetic organisms for biotechnological purposes. This includes using plants and algae for direct electricity production, and we recently described the world's first moss-powered radio receiver.
