Me and my planetary science

I am a planetary scientist interested in understanding the processes that modify the surfaces and lithospheres of the icy satellites, Io, Venus, Mars and Vesta. Studying these processes provides key clues for understanding how icy satellites and solid bodies formed and evolved. I analyze imaging data sets, map geologic features using GIS software and develop/use numerical (viscous/elastic) models (constrained by satellite gravity, topography and magnetic data). 

I am currently finishing up a project mapping and quantifying secondary craters on Ganymede and Rhea to improve age estimates of the outer satellites. I am also working on improving our understanding of Ganymede’s interior by applying potential field data techniques primarily used for resource exploration on Earth.

My past work has included the development and testing of a numerical model of Rayleigh-Taylor instability to explain coronae formation on Venus, estimating the thickness of the elastic lithosphere in the Northern lowlands of Mars using Mars Global Surveyor data, geologic mapping of the mid-latitude quadrangle V-12EW on Vesta (including the south polar structure) for the DAWN Science team and mapping grabens on Io using all available images from Voyager and Galileo.
