I'm a Ph.D. student, working on limit theorems of probability theory.

My activity on math.stackexchange consists in:

• trying to answer questions which didn't receive answers;
• upvote/downvote questions/answers;
• edits, retags of questions;
• review tasks;
• flag obsolete comments, answers which should be comments.

When I edit a post, I suggest the owner to check whether I didn't change the meaning.
