Who am I?
I grew up in Louth village, close to a town called Dundalk on the east coast of Ireland. In 1994 I went to live in the UK and study astrophysics at Cardiff University. There, I met my future wife (Roni) and generally had a four-year long party.
In the summer of 1998 we moved to California and I started graduate school in planetary science. I graduated from Caltech in May 2003.
From June-December 2003 I stayed and worked at Caltech as an assistant scientist with Prof. Bruce Murray. From December 2003 to Septemebr 2005, we lived in Boston while I worked as a postdoc at MIT with Prof. Maria Zuber.
After Boston, we moved to Flagstaff Arizona where I worked at the USGS astrogeology branch on the HiRISE project (even though I was employed by U. of A., don't ask... it was complicated). While we were in flagstaff we had our 3 (!) children, enjoyed the mountains and got to look at Mars at higher resolutions than ever before. We moved to Tucson in August 2007 when I started a faculty job at LPL.
