Roger Flower is a diatomist and freshwater ecologist with research interests in aquatic ecosystem change and diatom taxonomy. He has worked on lakes and lake sediments at sites throughout the world including the UK and Ireland, Russia (Lake Baikal), North Africa, the Falkland Islands and Canada (the oil sands region of northern Alberta). In the UK he has worked extensively on problems of surface water acidification using diatoms as indicators and he is currently collaborating with archaeologists on ancient water management issues regarding Egyptian lakes. He is responsible for diatom quality control in the UK Acid Waters Monitoring Network.
