**I am a graduate student of Mathematics at UCLA, under Professor** ** Terence Tao.**

**I expect to receive my Ph.D. degree in June, 2017. **

**My research interest lies in: **

- Quasirandom Groups and Expansion Type Results in Groups
- Combinatorial Group Theory and Geometric Group Theory
- Geometric Billiards and Veech Surfaces

**Here's my** ** Curriculum Vitae** **and my** ** Research Statement.**
