Research

My research focuses on applying multi-agent and game-theoretic techniques to the challenges of the future energy grid -- the smart grid --  with particular focus on problems of controlling of large numbers of small distributed energy resources. My specific interests are: 

-    Learning in games with applications to distributed optimisation, including algorithms for games with unknown noisy rewards or noisy action observations,
-    Dynamic team problems as a methods of distributed optimisation, e.g. dec-MDPs, MA-POMDPs,
-    Preference elicitation methods for sequential and combinatorial allocation problems,
-    User behaviour predictions and demand response models,
-    Home energy management and optimisation,
-    Cost division for network infrastructure.

Bio

Archie completed a B.A. and B. Econ (Hons) at the University of Queensland in 2003 and 2004, respectively, before working as an economist in the Queensland Public Service.  In 2006 he joined Electronics and Computer Science at the University of Southampton, under the supervision of Nick Jennings and Alex Rogers at Southampton, and David Leslie at the University of Bristol.  During his PhD and subsequent post-doctoral fellowship, he investigated game–theoretic and reinforcement learning techniques for optimisation and control in large distributed systems.  He returned to Australia in 2011 to complete a Postdoctoral Fellowship with the Discipline of Business Analytics (previously Operations Management and Econometrics) at the University of Sydney In mid-2012 he commenced working as Research Fellow in Smart Grids in the Centre for Future Energy Networks at the University of Sydney's  School of Electrical and Information Engineering.
