About Me

I am a full-time professor and researcher in mathematics at the Faculty of Sciences of the National Autonomous University of Mexico (FC-UNAM).

My main areas of research interest are discrete and computational geometry. I have strong programming skills in Python and web development. I keep on learning continuously and I like to share with others what I have learnt. I am open to research collaborations and interactions with industry.

I am particularly fond of mathematical problem solving. When possible, I contribute to various mathematical competitions around the world, including the International Mathematical Olympiad, the Asian Pacific Mathematics Olympiad and the Mexican Mathematical Olympiad.

I have various hobbies. I like painting, playing music, reading and the occasional writing of short stories or blog entries. I love cooking, specially mexican food and desserts. I have run some 10k races and a half-marathon.
