Professional summary

Tim's research focuses on the application of molecular tools to understand the composition and function of communities, within terrestrial and fresh water ecosystems - combining functional and molecular analyses to improve our understanding of biogeochemical cycles, sustainability and anthropogenic impacts.

Tim is a technical lead for DNA sequencing within the Molecular Ecology laboratories, providing training and support to students and researchers in molecular techniques and data processing.
