My research fields are astrobiology and planetary science. My research focuses on trying to answer several big questions:
1) How common are Earth-like planets?
2) What can the origin and evolution of life on Earth tell us about life elsewhere in the universe?
These questions can be divided up into: How did the Earth form? What is the chemical relationship between the Earth and the Sun? What is the age distribution of stars in the universe with enough refractory elements to make protoplanetary disks out of which a wet rocky planet could be made? What can the statistics of multiple planet systems recently discovered by the Kepler Space Telescope tell us about the architectures of planetary systems? My approach to answering these questions often involves the compilation and comparison of data from different fields (e.g. see Figure)
