NEW! Shawn
recently joined the Impact Field Studies Group
and the Mars Crater Consortium
NEW! Shawn is presiding this Mars: Inside and Out Poster
session at AGU
Research Description:
My research concerns the
remote sensing applications of impact craters and focuses on using remote,
field, and laboratory thermal infrared data of impact crater materials (such as shocked lithologies, impact
glasses, and impact melts) to better understand the surface composition of the
terrestrial planets. Mars and basalt
have been a recent, popular topic, but I prefer to travel to and study
terrestrial craters as analogs for Mars.
Previously, ASTER thermal infrared data of Meteor Crater, Arizona
was used as a proxy for examining similar (small, simple, and
well-preserved/”fresh”) impact craters on the surface of Mars with THEMIS
thermal infrared (and visual and near infrared, if available) data. For more information, here is a link to the IVIS Project Page and my
Master of Science thesis is now available here.
More details concerning
recent research using Lonar Crater, India as a terrestrial analogue
for Mars is coming soon.
