I
am a planetary scientist, and thus get to work in the exciting playground
that is our solar system. My research focuses primarily on three moons:
Saturn's moon Titan, Jupiter's moon Io, and our own Moon. The Cassini (http://saturn.jpl.nasa.gov) spacecraft has been in orbit around Saturn since 2005,
and with its array of diverse instruments it has discovered many fundamental,
new things about the Saturn system. Using the Radar instrument, I work
with the Cassini Radar team to understand the
surface processes on Titan that form such features as dunes, mountains, and cryovolcanoes. The
Galileo (http://galileo.jpl.nasa.gov) spacecraft spent
nearly ten years in orbit around Jupiter, and like Cassini,
it brought to light many complex and exciting characteristics of the Jupiter system.
I study active volcanoes on Io, specifically the distribution and
thermal output of volcanic eruptions from Galileo SSI visible-near infrared
images. This will lead to an understanding of the formation and evolution of paterae on Io, large volcano-tectonic depressions that
resemble volcanic calderas on Earth. In preparation for astronauts'
return to the Moon, we seek to study the Moon both from the ground, from orbit,
and from its surface. In particular, we are interested to know if there
is still subsurface activity of any kind that manifests itself at the Moon's
surface in various ways.
