I am a postdoc at U Michigan (Ann Arbor). I was a graduate student at Harvard, where my advisor was Dennis Gaitsgory, and I graduated in the spring of 2011. In short, I do geometric representation theory, which in the case of my thesis means perverse sheaves on the affine grassmannian with some gerbes thrown in, but could also mean something much more elementary.
I'm also active on tex.stackexchange.com.

Are there any books that take a 'theorems as problems' approach?
@paulgarrett If I understand you correctly: I've never understood why people like this book so much either. |

Why do roots of polynomials tend to have absolute value close to 1?
@Andrej I noticed the slight tendency of the roots to cluster near 1 and to disperse more near -1, and I'm curious if anyone can provide a statistical explanation to explain this effect. It does seem that there is a strong tendency to be nearly uniform, and this is sort of a second-order thing. |

What are $( \infty , n)$-categories useful for?
Seems to me that $(\infty, 1)$-categories are supposed to be considered as an enrichment of the concept of just "category"; i.e. they are not higher categories so much as they are deeper categories. Then $(\infty, n)$-categories are deeper, higher categories. Do you think that ordinary higher categories (i.e. 2-categories, 3-categories, etc.) are useful? If so, then their infinity version must be even more useful. |

Neither $-1$ nor 0 works, as they are contained in every field. |
