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.
+ 29 Jul 2020 - Go Perseverance! Launch day is tomorrow morning, and everyone is getting pumped Go to the launch site here for an out of this world experience. Also coming up is a talk to Australian school kids, here.
+ 02 Jul 2020 - Our EOS article just came out, it is a short 1500 word summary that highlights some of the findings of the JGR paper published earlier this year, and also talks about the similarities and differences between the ancient Pilbara rocks and the ancient Nili Fossae rocks. It also makes the point that both Earth and Mars were more similar at that time than they are today.
+ 28 Apr 2020 - I am now working on a Decadal Survey white paper focused on the science that could be gained by sending a multichannel, polarization sensitive LIDAR to Mars, as discussed in this paper. If you are interested in being a co-author or even just a collaborator on this white paper, feel free to email me and let me know! If you are working on a White paper that you think I might be interested in, please contact me!
+ 10 Apr 2020 - Dr. Carol Oliver, a Senior Research Fellow at the University of New South Wales, made me aware of a fantastic video that was made by her students regarding their investigations into the history of our understanding of the 3.5 billion year old Pilbara Region of Western Australia. If you are interested in the beginning of life and our history on this planet, I highly recommend you view it - they've made an effort to capture the science behind the ancient rocks as we understand it today, and still present a compelling and strongly resonating message that will stay with you long after you've closed up your computer. The students are Ashleigh Ford, Davey Dor and Mira Jordan (all University of New South Wales students).
All three were students in Carol Oliver's final year astrobiology elective, BEES6741 Astrobiology: Life in the Universe. This unit is fully online, you can reach it here at the online course page. (BEES is School of Biological, Earth and Environmental Sciences).
+ 8 Apr 2020 - NASA Astrobiology published a new article on the 'Serpentinisation and Astrobiological Potential of the Mars2020 landing site', which is a summary of our 2020 paper, please some more details.
+ 12 Mar 2020 - The SETI Institute published a new report on the paper, which is the result of work with the NAI node at the Institute. ' Mineral Link Identified Near Mars 2020 Landing Site ', SETI Institute News
+ 3 Mar 2020 - The Lunar and Planetary Institute (LPI) Planetary News published a short summary of the paper- An Olivine Protolith for Carbonate in Nili Fossae, Mars', LPI Planetary News
+ 21 Feb 2020 - AGU published our latest paper in the Journal of Geophysical Research, available online as a free PDF here: 'Olivine-Carbonate Mineralogy of the Jezero Crater Region'
+ 24 Apr 2019 - We submitted our first version of the manuscript to JGR.
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.
