Joshua Dean is a UKRI Future Leaders Fellow and Senior Lecturer in the School of Geographical Sciences at the University of Bristol, UK. Prior to this, he was a Lecturer in Biogeochemical Cycles at the University of Liverpool. His research is at the intersection of hydrology and elemental biogeochemistry. His work combines isotopes, biogeochemical and hydrological fluxes, and microbial community characterisation to quantify the source, transformation and flow of carbon through the land-freshwater-atmosphere continuum. His current main research focus is methane cycling and the application of radiocarbon as an unconventional tracer in the global carbon cycle. Originally from New Zealand, Joshua has enjoyed working in many fieldwork locations including the East Siberian Arctic, Northwest Canadian Arctic, the Yucatán Peninsula, southeast Australia, and across the UK and Europe. Joshua received his BSc (Hons) in Geography from Massey University in New Zealand, and his PhD in Hydrogeology from La Trobe University in Australia.
