About Me

I am a Founding Scientist at Pluralis Research, where we are making large-scale decentralized training feasible and practical. Additionally, I hold a Visiting Researcher position at the Australian National University. Previously, I spent 4 years as a Senior Machine Learning Scientist at Amazon Australia working on cutting-edge machine learning applications. Before that, I was a Postdoctoral Research Fellow for 3.5 years, with 2 years at the Australian Centre for Robotic Vision (ANU) and 1.5 years at the Torr Vision Group (University of Oxford). I obtained my PhD from the Australian National University in May 2017, where I was primarily supervised by Prof. Richard Hartley. My research spans Optimization and Machine Learning, with the current focus on robust and efficient decentralized training algorithms.
