Dr Katharine Pemberton

Biochemist, PSTT Fellow

Before teaching, Katharine worked as a researcher in aquatic science. She gained her first degree in Marine Biology at the University of Newcastle upon Tyne and then began her PhD research at Plymouth Marine Laboratory.

During her PhD, Katharine investigated different ways of measuring and estimating primary production in the marine environment. An understanding of primary production is really important to help scientists make predictions about levels of carbon dioxide in the atmosphere, to help understand climate change. The research showed that different measurement methods gave different estimates of primary production, which, when extrapolated to global scales, could lead to huge variations in climate change predictions.

After her PhD, Katharine took a post-doctoral research post in Canada. The aim of the project was to link in situ estimates of photosynthesis to water quality in the Laurentian Great Lake. The research showed that rates of photosynthesis could indicate the presence of particular species of phytoplankton. The presence of certain species of phytoplankton have a negative impact on water quality.

Having visited schools as a researcher, Katharine discovered how rewarding teaching could be. After having children, she moved back to the UK with her husband and retrained as a primary teacher. She has been teaching at Modbury Primary School in Devon for the last five years.
