I spend my time in the Head lab, where I try to see things that have never been seen. Almost everything has been seen in two dimensions, so I get paid to add a third: depth by visualizing images of other planets in stereo, or time by acquiring long-duration time-lapse photography of the McMurdo Dry Valleys in Antarctica. If I can make sense of something, I'll write a paper about it (below). I also write code to process data and do lots of GIS work, but that's enough about that. With a primary interest in ice, I spend most of my time on Mars, but that doesn't mean I won't work with data from Mercury, the Moon, and even Venus from time to time.
