2017 - present: Post Doctoral Research Associate

Working on a project to characterise the martian water cycle by assimilating ExoMars 2016 Trace Gas Orbiter data

2015 - 2017: Post Doctoral Research Associate

Working on the data assimilation work package of the Horizon 2020 UPWARDS: Understanding Planet Mars project.

2011-2015: PhD Research Student

Focusing on trace gas assimilation in the Martian atmosphere

Research interests

I am a post-doctoral researcher who primarily investigates atmospheric chemistry cycles on Mars using a combination of observations and computer modelling. My research is helping to investigate links between the atmospheric chemistry cycles and the main drivers of atmospheric processes, such as the dust and water cycles, by combining computer models with the latest observations from the ExoMars Trace Gas Orbiter mission alongside multiple other spacecraft missions.

  • Atmospheric chemistry cycles on Mars

  • Escape of water from the atmosphere of Mars

  • Global Circulation Modelling

  • Mesoscale Modelling

  • Data assimilation: combining retrievals with computer models

  • Forecasting of martian weather

  • Human exploration of Mars
