I was born in Bogota, on July 21st, 1984. I started my undergraduate mathematics studies in 2001 at Universidad de los Andes, motivated by my participation in several national and international math olympiads while I was in highschool. During the time I spent at the university, I participated in the International Mathematics Competition for University Students obtaining good results. My fascination for mathematics increased every day, in several different areas such as combinatorics. This work on the Shi arrangement was made during the last year of my undergraduate studies, and was presented as part of my thesis, under the direction of Federico Ardila. Iím now finishing my master studies at the same university, and I hope to start my doctorate program in 2007 (if I can overcome the sadness of leaving Colombia).
