Hi! You've reached an online cache of Peihong Jiang.

I am a 4th year PhD student in Mathematics at Brown University. My advisor is Prof. Jeffrey Brock.

My current research interest has been gradually shifting towards low-dimensional topology and geometric group theory, mostly Mapping Class Group and Out(F_n). Somewhere along the way I became a big fan of various associated complexes.

A while ago I was pretty commutative. Even before that I was (unbelievably) numerical. Once upon a time I thought I'd do K-Theory/Abstract Homotopy Theory, but that did not happen. If you are interested in teaching me TQFT or Quantum Random Walks, that'd be cool.

I'm also an avid climber and an adjunct programmer. If none of the above is allowed, I'd be reading/listening to music/experimenting with food/taking a random walk by myself (or with fellow travelers??).

I am a Teaching Assistant for MATH90 (Calc I) in the Fall. Teleport to the course website.
My Current Office Hour is TBD...

I will be a Teaching Fellow for MATH200 (Multivariable Calc for Physics & Engineering) in Spring 2017.

'All, everything that I understand, I understand only because I love. '- Lev Tolstoy

At some point in my life, I thought algebraic closure was safe, while chalkboards and splitting fields were dangerous. The picture was taken at SMALL 2013.

I have more dimension than my webpage. Maybe we'll meet in real life some day.
