A mathematics enthusiast caring to help others out. When applicable, in the process of answering/helping out, I point people to the community effort http://www.proofwiki.org which catalogs and rigorously founds proofs in all areas of mathematics.

My most knowledgeable areas are logic and category theory. I also know a fair share about measure theory and functional analysis, along with the standard undergraduate curriculum.
