I am interested in machine learning and its applications to vision-and-language tasks. I have had the experience of working at Australian National University (ANU), NICTA (currently Data61), Microsoft Research, Xerox Research and NEC Labs America prior to joining AIML.

We are actively looking for PhD and postdoc candidates. If you are interested, feel free to contact me.
