Time-domain electromagnetic sounding in southern Nevada. Sarah Gonzalez (SwRI) operates the Geonics Protem while Bob appears to be distracted. Exploration geophysicists spend a lot of their field time looking at orange boxes.

I'm a geophysicist with interests in both planetary and terrestrial exploration. Much of my work through the mid-90s was on the geodynamics of Venus. I have also investigated the thermal, collisional, and hydrogeological histories of meteorite parent bodies.

I spent several years in industry, specializing in seismic exploration (particularly for detection of gas in naturally fractured reservoirs), electromagnetic discrimination of unexploded ordnance (UXO), and electrical detection of soil contaminants.

During my industry "sabbatical," I discovered that electromagnetic methods in particular are ripe for application in the search for groundwater on Mars. In parallel, I work on aspects of the role of groundwater in geological processes on Mars. I am interested in developing new instruments and missions, particularly for Mars exploration. Supporting facilities provide laboratory and field ground-truth for instrument development and testing.

My current research focuses on the geophysics and hydrogeology of Mars and asteroids, and electromagnetic sounding of planetary interiors.


A geological cross-section of Boulder, CO, is fun to ponder and more fun to hike.

Like fire, humans are drawn to the mystery of the orange box.
