There are three kinds of food.

One is the food that your mother makes for you. One is the kind of food that you eat in restaurants. One is the kind of food that you eat in dreams.

I am far too interested in listening to music, watching movies, and reading new weirdish literature. My work relates to PDEs and quasiregular mappings in the plane and space.
