Postdoctoral researcher

Member LEAR Team, INRIA Rhone-Alpes, Grenoble, France.

I research image/video classification problems, kernel methods and deep learning. I worked with Dr. Julien Mairal, Dr. Zaid Harchaoui and Dr. Cordelia Schmid.
I have joined the NICTA/Data61 Canberra Research Lab in August, 2015.
