Welcome

Welcome to my science home page. Information on my research projects, the NASA and European Space Agency (ESA) missions that I am involved with, and links to relevant planetary science sites are contained on these pages.

Currently I am working as a Research Scientist at NASA Ames Research Center in Mountain View, California. My research specialties include the geology of Mars and the icy satellites of the outer Solar System.

Mars Exploration

Mars has more active spacecraft missions than any other planet in the Solar System, except for Earth. Forty years ago, we knew very little about the surface, history, geology and weather of Mars. Now we are receiving new high-resolution data every day from the Red Planet! Planetary scientists who currently study Mars have access to data from the following current missions:

Icy Satellites

Studying the histories, geology, and surface features of the icy satellites of Jupiter, Saturn, Uranus, Neptune, Pluto, and Charon are another of my specialties. Data that I study comes in part from:
  • The New Horizons mission to Pluto. I am on the imaging team for this mission. In 2010, the spacecraft is almost halfway to Pluto, a journey that will take more than ten years!
  • The Cassini mission to Saturn. With its beautiful, complex rings, Saturn has over 60 satellites, including Enceladus, an icy moon that spews water into space from cracks on its surface.
