I am interested in cities as spatially and geometrically constrained complex systems. I explore how spatial and socio-economic processes interact, and how these interactions lead to morphological transformations and scaling. I like to think with data-driven analytics as well as physics-driven models. I am also interested in the structure and behavior of complex systems in the engineering and biological domains.

Ongoing Research Projects
- AHURI Stand-Alone Project on New housing supply, population growth, and access to social infrastructure: This project will develop a monitoring framework, to assist as a policy coordination tool, which correlates the development of new residential supply and potential population growth against the delivery, spatial density/distributions of, and accessibility to social infrastructure, based on case studies of greenfield development sites across Sydney, Brisbane and Perth.
- Urban Studies Foundation Grant on Predicting Neighborhood Change using Big Data and Machine Learning: Implications for Theory, Methods, and Practice: Joint project with Prof. Karen Chapple at University of California, Berekeley: A January 2020 workshop is upcoming.
