Dr Rebecca Ellis
Biologist/Engineer, PSTT Fellow
After achieving a 1st class BSc (Hons) studying Biology at Bristol University, Rebecca had her first taste of research working at the Natural History Museum, London for the Parasitic Worms Department. She then moved to Cranfield University and began her four year Engineering Doctorate (EngD) on the 'Development of a Novel Medium to Improve the Performance of Biological Aerated Filters (BAFs)'.
Generally used as a secondary sewage treatment process, BAFs provide a high rate, compact solution through maintaining a concentrated biomass in the form of a biofilm. The medium to support the biofilm also removes suspended solids by depth filtration and so regular backwashing is required. With industrial sponsorship from English China Clays International, Rebecca worked for 6 months 'in house' at St. Austell where she could engage with the clay foaming process directly and use Environmental Scanning Electron Microscopy to observe biofilm growth.
After leaving research, she gained a PGCE from Bath University. She has taught for 18 years at a junior school in Warwickshire and has two children.
