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.
See Google Scholar for the full record of my publications.

News:
Two WACV'19 and one IJCV papers accepted. Congrats Fatemeh Shiri and Hongguang Zhang!
I am organising an ACCV 2018 workshop and a mini-challenge entitled Museum Exhibit Identification Challenge (Open MIC) for Domain Adaptation and Few-Shot Learning.
The Open MIC dataset is available for non-commercial academic research Open MIC Dataset (ECCV 2018).
I am serving as an Area Chair for WACV 2019, ICLR 2019 and ICCV 2019.
Two ECCV'18 (oral ~2% acceptance rate/poster) and one BMVC'18 (spotlight ~6% acceptance rate) papers accepted. Congrats Yusuf Tas and Tsung-Yu Lin!
Two CVPR'18 and one WACV'18 papers accepted. Congrats Fatemeh Shiri and Hongguang Zhang!
I have been listed as an Outstanding Reviewer by ICCV 2017, CVPR 2017 and ECCV 2016 Awards Page.
I am organising a full-day CVPR 2017 workshop entitled Tensor Methods in Computer Vision with my colleagues Anoop Cherian and Fatih Porikli.
I am the main advisor for three PhD students at CECS/ANU: Fatima Shiri, Yusuf Tas and Hongguang Zhang. I am co-supervising (second supervisor) Christian Simon with Dr. Mehrtash Harandi.
I have been listed as an Outstanding Reviewer at CVPR 2015 Awards Page.
Code for Convolutional Kernel Networks is here.
