Welcome to my website. I am a planetary scientist working at NASA Headquarters in Washington D.C., where I am the Deputy Program Scientist on the Mars2020 rover mission. My fields of research include Mars, astrobiology and remote sensing spectroscopy. On this website you'll find an introduction to my research, including my community products, as well as my research papers and projects.

My current research focuses on the analysis of data from the Mars instrument "CRISM" which is onboard the Mars Reconnaissance Orbiter (Mister Oh).

Here are two Wordle maps showing the frequency of usage of words in the abstracts of my first 10 scientific papers.

My scientific work involves understanding the way light interacts with solid surfaces. I'm interested in furthering our understanding of all aspects of the way electromagnetic waves interact with particulate surfaces (especially snow or ice packs, where we can characterise the components better than soils or rocks).

I completed my PhD studies at the Australian Centre for Astrobiology. If you are interested in my PhD research on hyperspectral mapping of ancient hydrothermal systems in the Pilbara region of Western Australia, you will find the web site, and many linked resources, here.
