I've been an assistant professor at the PTYS/LPL since fall of 2007. I moved from Ireland to the United States in 1998 to pursue graduate studies in planetary science at the California Institute of Technology. After five enjoyable years in Pasadena, I spent two years in both Boston at the Massachusetts Institute of Technology) and Flagstaff at the U.S. Geological Survey) as a postdoc. My wife and I now live in Tucson with our three kids, two cats, one dog and assorted fish. Despite or maybe because of) growing uon an island where billions of tons of water fall out of the sky each year, I like the desert and enjoy hiking and camping when possible.
