Research activities

THIS PAGE IS A MAJOR WORK IN PROGRESS. I'M HOPING THAT IT WILL EMBARASS ME ENOUGH TO ACTUALLY BE MOTIVATED TO FINISH IT.

The following is a laundry list of things I'm working on or have already written papers about. You can take a look at my publication list if you would like to download a copy of these papers. I'm hoping to flesh this out with details of different projects as time goes by.





Modeling of martian polar cap geomorphology




Water frosts on Ceres




Permanent shadowing on the Moon and Mercury




Landscape evolution on airless bodies




MOLA Radiometry




Fractal Topography

One thing I've gotten interested in recently is the statistics of small-scale topography. It's really amazing how nature arranges itself so that properties at one scale are related to properties at another.

The fractal dimansion describes how long-wavelength power is propagated to short-wavelengths. In this perspective view, red is high topography and blue is low; the absolute horizontal and vertical scales are arbitrary.

Deviations from behavior like this usually indicates different processes operating over different lengthscales. The martian north polar ice cap is one of the smoothest places on Mars at the 100's meters scale but extremely rough at the 10 meter scale.
