2021 - present: UK Space Agency Aurora Research Fellow

Investigating interactions between the global dust and water cycles on Mars through an analysis of orbiter observations from the ExoMars Trace Gas Orbiter (TGO) (among others) in preparation for the upcoming ExoMars Rover mission. This research will combine TGO observations with an internationally recognised Mars Global Circulation Model (GCM) utilising proven data assimilation techniques to give new insights into the martian dust and water cycles and providing a longer-term framework to support future Mars exploration missions such as Mars Sample Return.

2017 - 2021: 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 UK Space Agency Aurora Research Fellow 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

This proposal seeks to answer fundamental questions about the interaction of the global dust and water cycles on Mars through an analysis of orbiter observations from the ExoMars Trace Gas Orbiter (TGO) (among others) in preparation for the upcoming ExoMars Rover mission. This research will combine TGO observations with an internationally recognised Mars Global Circulation Model (GCM) utilising proven data assimilation techniques to give new insights into the martian dust and water cycles and providing a longer-term framework to support future Mars exploration missions such as Mars Sample Return. The specific aims of this proposal are: A1. To determine the spatial and temporal influence of smaller regional dust storms on the general circulation and transport of water vapour/ice and water isotope D/H ratios. A2. To quantify the loss of water and its variability over a combined 11 Mars years (containing two global dust storms) and determine the associated change in global water isotope D/H ratios. A3. To predict the dust conditions and vertical profile of atmospheric properties for the ExoMars Rover and Surface Platform (RSP) entry, descent and landing. A4. To build a framework for long-term, global-scale assimilation of key atmospheric variables to inform local scale weather determination, in support of future exploration missions
