Dr Joel Davis

Postdoctoral Researcher, ExoMars

Department: Earth Sciences
Division: ES Mineral and Planetary Sciences Division

Summary

I am a postdoctoral research assistant in the Department of Earth Sciences. My work uses remote sensing data from satellites to further understand the geology of ancient and modern Mars. I am interested in a variety of surface features and environments on Mars, such as ancient rivers and lakes, sand dunes, and glaciers. Much of my work focuses on understanding the nature of ancient river and lakes found on Mars' surface, and what they could mean for the evolution of the planet. I have been involved in the characterisation of the candidate landing sites for both the ExoMars 2020 and Mars 2020 rovers.
