Biography:


I am a Research Associate at the Centre for Atmospheric Science in the Department of Chemistry. I work in the atmospheric modelling groups of Prof. John Pyle and Dr Alex Archibald with the global United Kingdom Chemistry and Aerosols (UKCA) version of the Met Office's Unified Model System (HadGEM3-GA-UKCA). My work on chemistry-climate interactions contributes to the continued development of the atmospheric chemistry scheme in this model. This is a collaborative effort towards the development of the forthcoming new UK Earth System Model.


Previously I worked as a Research Fellow at the University of Birmingham on global modelling of cirrus clouds and their role on climate-relevant processes in the Tropical Tropopause Layer. As a Lecturer in Climate-Environment Interactions at King’s College London I gained extensive experience in developing lecture courses, and in teaching and examining on a wide range of subjects in atmospheric science and climate change. In earlier research at the University of Cambridge I worked on quantifying the impact of the global aviation sector on atmospheric composition and climate change.


I obtained my Ph.D. in Atmospheric Chemistry from the University of Cambridge and my first degree in Meteorology from the University of Karlsruhe (now KIT) in Germany.


 


Research Interests:


  • Atmospheric chemistry-climate interactions and composition change
  • Numerical modelling of atmospheric processes
  • Cirrus clouds and their role in atmospheric chemistry in the Tropical Tropopause Layer
  • Impact of aviation (and other transport modes) on atmospheric composition change and climate

Projects:


  • I am completing my work into the varibility of cirrus cloud coverage in the tropical Pacific due to ENSO phase changes in connection with the CAST project.
  • My work contributes to the ACSIS project which investigates decadal and inter-annual changes in the North Atlantic Climate system. I am preparing transient free-running and nudged model integrations with the HadGEM3-GA-UKCA model to investigate changes in atmospheric composition and chemistry in comparison with in-flight measurements. This work is in collaboration with the NCAS atmospheric science community and other NERC Centres in the UK.
  • Together with Paul Griffiths and Alex Archibald I contribute to the “Oxidant Budgets of the Northern Hemisphere Troposphere Since 1950” (OXBUDS) project, also in collaboration with colleagues at the University of East Anglia. In this project I will implement a diagnostic alkyl nitrate chemistry scheme into the latest version of the HadGEM3-GA-UKCA model and carry out multi-decadal test integrations, validated by airborne observations and measurements from firn air.

 


Teaching:


I presently work in a full-time research role and my teaching duties are set to a minimum. I am a superviser for Year 3 and Year 4 atmospheric chemistry tutorial groups (Parts II and III of the Natural Sciences Tripos) in the Department of Chemistry at Cambridge.


As a Research Fellow at the University of Birmingham (2013-15) I have supervised and examined MSc dissertations in Physical Geography.


As a Lecturer in Climate-Environment Interactions at King’s College London (2008-13) I have developed lecture- and seminar-based courses, taught and examined extensively over five years in Physical Geography, from undergraduate courses to Ph.D. level, on a wide range of subjects including atmospheric science, climatology, air pollution and biogeochemical cycles. I have been director of the taught postgraduate programme "MSc in Carbon: Science and Society" and admissions tutor for a number of postgraduate taught programmes.


After obtaining the Postgraduate Certificate in Academic Practice (PGCAP) at King’s I became a Fellow of the Higher Education Academy in 2012.
