Research Interests

I am interested in solving planetary science/remote-sensing problems using a variety of computational approaches. Primarily, I am interested in:

• Understanding the role that water has played in altering the martian surface/subsurface and what implications this may have for palaeo-habitable environments.
• The chemistry of martian brines, thier episodic formation at the surface and how they affect subsurface mineralogy.
• The thermal behaviour of surface materials and how diagnostic thermal signals can be used to map geologic units.
• The role that atmospheres play in altering planetary surfaces over geologic time.

To understand the geology of a planet from orbit I model thermal behaviour of planetary surfaces, analyse topography, identify minerals detected in IR absorption spectra and conduct geologic mapping in a GIS environment using visible, infrared, hyper-spectral and topographic datasets acquired by ESA/NASA orbiters, landers and rovers.
