Research Themes

My research is centred around understanding the role of volatiles in the evolution of planetary surfaces through geomorphological techniques. The ultlimate aim is to be able to constrain the volatile-cycles and the history of volatiles in the solar system through the study of planetary bodies. My current research themes are:

1. Understanding the recent climate and hydrological cycle of Mars using gemorphological techniques. In my recent work I have used hydrological techniques developed in terrestrial geomorphology on high resolution digital terrain models of km-scale gullies on Mars. The origins of these features are debated - they resemble water-carved gullies on Earth, but could be formed by CO2 sublimation processes. Through this comparison we concluded that liquid water was the most probable candidate for their long-term formation. Continuing work includes detailed topographic studies and testing against global climate model data. Collaborations include: Utrecht and Open University.

2. Laboratory simulation to understand sediment transport mechanisms on Mars. In order to understand the potential impact on the landscape of both metastable water and sublimating CO2 I am in the process of performing experiments in the Mars Chamber at the Open University in the UK. This work is being perfomed in collaboration with the Open University, Arkansas University and Paris-Sud. 

3. Remote sensing studies in order to understand the role of volatiles in surface processes of Mercury, the Moon and Vesta. This research strand is intertwined with my martian studies, and on Mercury forms the basis of the projects of PhD students I co-supervise at the Open University.

4. Degredation of permafrost and its impact on mass wasting processes (landslides and debris flows). A collaborative project with the University of Iceland and Open University, UK and the core-theme of a NERC CENTA studentship hosted at the Open University.
