I am currently a PIMS postdoctoral fellow at University of British Columbia.
My research area is Optimization.
My mentor is Professor Michael Friedlander.
This is my CV.

I am on the job market this year.

I received my Bachelor degree in 2004 from the Chinese University of Hong Kong, Department of Mathematics. I got my MPhil degree in 2006 in the same department under the supervision of Professor Kung Fu Ng. I started my PhD study in 2006 in Department of Mathematics of University of Washington, under the supervision of Professor Paul Tseng. After the disappearance of Professor Tseng, I was coadvised by Professor Maryam Fazel and Professor Rekha Thomas. I was in Simon Fraser University from July 2010 to March 2011 working with Professor Zhaosong Lu as a visiting researcher. I got my PhD degree in June 2011. From June 2011 to July 2013, I was a postdoctoral fellow at University of Waterloo, under the mentorship of Professor Stephen Vavasis and Professor Henry Wolkowicz.

**Broadly speaking: ** Convex optimization

**Current focus:**

- Convex relaxations (e.g., for sensor network localization);
- First-order methods for large-scale problems;
- Matrix rank minimization.

- Constraint qualifications for convex optimization.
