We are organizing the **UCSB Differential Geometry Seminar**.

I am a member of the Geometry group. Before moving to UCSB, I was a CLE Moore instructor in the Math department at MIT. I received my PhD from Stanford University in 2013 with Richard M. Schoen as my advisor. Here is my **Curriculum Vitae**.
