About Me

I am a fifth year Phd student mainly interested in Differential Geometry, graduating this year. My advisor is Christopher Croke. I am going to visit Max Planck Institude of Mathematics at Bonn for a year. After that, I will have a postdoc position at Notre Dame for three year, starting in Fall 2015. Here is my CV.
