Key Facts:

Joanna joined the department in October 2010. She completed her PhD on dissolved organic carbon dynamics in blanket peat in 2005 at the University of Leeds in collaboration with CEH Merlewood/Lancaster (NERC-CASE). She then worked as a Research Fellow on three projects based at Imperial College, Bangor University and the University of Leeds:

Sensitivity of peatland carbon cycling to climate change (Grantham Institute for Climate Change, Imperial College)
Vulnerability of upland peatland ecosystem services to climate change (Environment Agency and NERC-QUEST)
Influence of recovery from acidification on the dynamics of dissolved organic carbon in organic soils (NERC)

Joanna is currently on the Editorial Board for Scientific Reports. Joanna was a Guest Editor for a special issue of Climate Research on Climate Change and the British Uplands.
