I'm a math faculty member at a university on the U.S.-Mexico border. I teach mostly future teachers. I have a background in differential geometry, global analysis, and applications to particle theory.

"Algebra is the offer made by the devil to the mathematician. The devil says: 'I will give you this powerful machine, it will answer any question you like. All you need to do is give me your soul: give up geometry and you will have this marvellous machine.'" (Michael Atiyah)
