I was born in '74 in Santiago, after the coup. So I grew up listening about the UP, militaries and communists. With virgin lungs of the winds of democracy. When I was I kid I used to play in "La Plaza Ñuñoa", where my parents used to live, way before it became Ñuñork. I learnt what the teachers where supposed to teach at the Colegio Calasanz, who saw me grow for 13 years. Wild years when I thought I could fight the establishment (teachers) and bring new blood (us, the students) to the school. As president of the student union I managed to get a respectable number of enemies, both among the student and the teachers. From my parents I learnt (among some useless stuff as well) how good camping was. For long summers my skin got darker in the wonderful beach of Las Tacas. By that time I felt it belonged to me. I think that in their dunes is where my curiosity about the Universe started. After I finished school I decide to go for science, so I studied Licenciatura en Física at PUC. I met Claudia there. Good friends from the beginning... she is still my best friend, but now we have a small book where it says she is my wife. From autumn '96 until 2000 I was a student at the IoA in Cambridge, where I got my PhD in Astrophisics. Maybe the nicest thing about Cambridge, was the amount of friends we make at that time. Regardeless of the clouds somedays I miss riding my old black bike back home. After so much darkness and clouds we move to Pasadena in sunny California, where I was a research fellow at the Carnegie Observatories for the next two years. I didn't have enought time to learn to surf, but we did a lot of camping and road trips round the southwest and made many, many playitas at Manhattan Beach, maybe the best spot for playitas in southern California. After driving 5000 miles from California (see Map) we moved to Baltimore, Maryland where I work as an Associate Research Scientist at Jonhs Hopkins University.
