My research focuses on the interpretation of remotely sensed data to investigate the surface geomorphology and subsurface stratigraphic record of planetary bodies. I make extensive use of orbital radar soundings, high resolution satellite imagery, and digital elevation models. My research involves processing, interpreting and integrating observations from multiple types of remotely sensed data in collaboration with other researchers to deduce the evolution of planetary surfaces. Throughout my dissertation, my research has been focused on applying these approaches to the Mar's north pole.

Current Research Projects

Reconstruction of icy crater deposits surrounding the Mars north polar ice cap using SHAllow RADar data. Stratigraphic analysis indicates these deposits may be coeval to the massive Planum Boreum ice deposit, a striking discovery.

2013 LPSC Abstract
Abstract for talk on SHARAD radar and Korolev Crater. Talk will be given on March 21, 2013 at the Lunar and Planetary Science Conference in The Woodlands, TX

2012 LPSC Abstract
Abstract for a talk on investigation of Abalos Mensa, Mars. This feature is unique on Mars north pole as it is pure water ice but isolated by narrow chasmata from the polar cap. The wedge-like morphology of this feature also makes it unique. Talk given in March of 2012 at the 43rd Annual Lunar and Planetary Science Conference in The Woodlands, TX.

2011 LPSC Abstract
Exploration of reentrants found via careful mapping of SHAllow RADar data in the basal unit on Mars' north pole. These reentrants are predominantly located very near enigmatic modern landforms that have been difficult to understand using modern topography and conditions.

2010 LPSC Abstract
Abstract for a talk given in March of 2010 on the subsurface geomorphology of Mars' north pole basal unit. This feature was once believed to be a simple domed deposit of material; however, SHallow RADar mapping has shown the basal unit deposit to be surprisingly complex.
