Welcome

I am a Research Scientist at the Laboratory for Atmospheric and Space Physics at the University of Colorado. My main research interests are the geologic, hydrologic, and climatic histories of the planet Mars and all things related. In particular, I work on problems dealing with past fluvial erosion on Mars, martian volcanoes, geologic mapping, habitable environments, and aqueous geochemical modeling. New data, including high-resolution topographic data and images, are shedding light on the planet Mars and upcoming missions will continue to change our perceptions of this planet. I am involved with analysis of the Terra Meridiani region, which is the landing site of the Opportunity Rover. My mapping has helped evaluate hypotheses regarding the formation of the deposits.

Feel free to check out my personal info to learn what I do outside of work and see some neato pictures. I've also posted my curriculum vitae.
