About Me

Since December 2020 I'm a Machine Learning Scientist at Amazon Australia and also a Visiting Researcher at the Australian National University. Prior to this I was a Postdoctoral Research Fellow for 3.5 years, among which I spent 2 years at the Australian Centre for Robotic Vision at the Australian National University and 1.5 years at the Torr Vision Group at the University of Oxford. I obtained my PhD from the Australian National University in May 2017 and I was primarily supervised by Prof. Richard Hartley. I am broadly interested in Optimization and Machine Learning, and the specific topics I currently work on are listed below.
