Ruth Doherty is a Professor in Atmospheric Sciences at the University of Edinburgh, UK. She has a PhD in Astronomy from the University of Edinburgh (UoE) and an MSc in Environmental Sciences from the University of East Anglia (UEA). She carried out postdoctoral research at UEA and at the National Center for Atmospheric Research (NCAR) in climate variability and climate change impacts, and subsequently in composition-climate modelling at UoE. Her research focusses on multi-scale modelling of composition-climate interactions from global to street-scales. She has contributed to several international model assessments: Atmospheric Chemistry and Climate Model Intercomparison Project team (ACCMIP), the UNECE Task Force on Hemispheric Transport of Air Pollution (TF-HTAP) and on ozone-related health metrics for the IGAC Tropospheric Ozone Assessment Report (TOAR I). She collaborates with epidemiologists to investigate the health impacts of air pollution and weather and is currently leading research projects into the health co-benefits of Net Zero associated with outdoor-indoor air quality and extreme heat. She is a lead author for IPCC WG1 Chapter 2 (large-scale changes in the climate system and its causes) in its latest (7th) assessment cycle.
