I'm Ao Sun, a fifth year graduate student in the Department of Mathematics at MIT. My advisor is William Minicozzi.
I am interested in geometry and PDEs, especially minimal surfaces, constant mean curvature surfaces, and mean curvature flow.
Here is my CV.

### Some Notes

Some notes I took at many different places.

### Student Seminar

I am running the geometric analysis student seminar at MIT. In general every week we have a speaker talking about anything the speaker is interested in.

Note this is not the official Geometric Analysis Seminar at MIT.

### Other Activities

I am a George Lusztig PRIMES Mentor in year 2018. PRIMES is "Program for Research in Mathematics, Engineering and Science for High School Students" held by MIT.
I was the cheif editor of Hesi from 2013-2014 at Tsinghua University. Hesi is a student journal edited by students in Department of Mathematical Sciences, Tsinghua University.
