I am a fourth year PhD student in Department of Mathematics at University of Michigan.

I graduated from University of Illinois at Urbana-Champaign in June 2015.

I am interested in number theory. In particular, I am interested in the Langlands program related theories. More specifically, local Langlands mostly for now.

In Fall 2018, I am working as a tutor in MathLab.

From Fall 2013 to Spring 2015, I worked as a tutor/grader for Linear Algebra/Calculus I course in University of Illinois.

- Math 776, Class Field Theory, taught by Jeffrey C. Lagarias (course website is here). [pdf]
- A note on a Tate's theorem. [pdf]

Outside of math, I am interested in reading, swimming, hiking, planting, watercolor painting (especially about plants), cooking, sewing.

I am also particularly interested in hearing interesting ko-ans in Buddhism, you can definitely email me with the reference if you see a good one, thank you.
