Welcome to my
website. I am a planetary scientist
working at the SETI
Institute and NASA
Ames Research Center in
Mountain View, California. My fields of research
include Mars, astrobiology and remote sensing spectroscopy. On this
find an introduction to my research,
products, as well as my research
My current research
focuses on the analysis of
data from the Mars instrument "CRISM"
which is onboard the Mars
Reconnaissance Orbiter (Mister
Oh). My CRISM releated research
page is here.
Here is a Wordle map showing the frequency of usage of
words in the abstracts of my first 10 scientific papers.
For the CRISM
project, I am helping choose targets
analysing data from the North
Poles of Mars. I am working with
other researchers to
study seasonal changes in the surface and atmosphere in the
polar regions of Mars. The poles are the most dynamic regions on Mars
they may hold the history of past
On the community
page, you'll find datasets I've
generated that may be useful to other members of the planetary science
On the education
and Outreach side, I am the
coordinator of the SETI
Institute Seminar series - a
talk from cutting edge researchers in the Northern California region.
I also help teach
an online planetary science
course at the Astronomy
Department of Swinburne University
in Melbourne, Australia.
I am involved in
the running of the Australian Space Prize, which is an annual prize for
undergraduates who have completed an Honours thesis related to space in
science or engineering. The winner each year travels to a NASA Center
in the United States to take part in a 10-week summer program. More
details can be found here.

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

Reconnaissance Imaging Spectrometer for Mars (CRISM)
opened its cover in
September of 2006 and has been taking images ever since. Check out the
seasonal mosaics for the 2006 Mars southern polar recession, you can
