Dennis Meng

Started learning discrete mathematics in fall 2009, and didn't look back. I wouldn't call myself extremely good at it, but did manage a respectable score on the Putnam as a college senior in 2012.

I ended up with a discrete math minor in college, and still read up a little bit here and there. You'll occasionally find me lurking here in the number theory tag, or looking at puzzles and combinatorial games.
