Personal profile
Biography
Traffic systems, the weather and climate system are examples of complex systems. I am interested in understanding their dynamics based on the data they produce. I received a MSc and PhD from the Technische Universitaet Darmstadt in Germany, where my research was in the intersection between statistical physcis and dynamical systems. Afterwards, I joined UWA in 2007 as a post-doctorial researcher on improving state estimation and forecasting in dynamical systems with applications to weather forecasting. Since 2009 I hold a teaching and research position at UWA.
I am a member of the Complex System Group within the Department of Mathematics and Statistics. My research is focussed on fundamental advances and applications in the area of complex systems and dynamical systems theory. My research is driven by applications and open questions in various areas. This includes my research on traffic modelling and analysis within PATREC and ocean dynamics within ARC Research Hub for Transforming Energy Infrastructure Through Digital Engineering.
Research interests
My research lies broadly in the fields of Dynamical Systems Theory and Complex Systems Theory. It is driven by real-world problems and grounded in data, with a focus on developing mathematical methods and algorithms tailored to specific challenges. In particular, I am interested in addressing complex problems arising in climatology, ocean and traffic dynamics as well as modelling.
I adopt a multidisciplinary approach that combines modern computing, analytics and simulation techniques to contribute to the following research problems:
- Transport and traffic modelling and simulation;
- Data analytics (Machine Learning etc.) for transport;
- Uncertainty quantifications with applciations to wave propagation;
- Non-linear time series analysis for paleo-climate analysis.
Funding overview
My research received funding from the ARC and the offshore industry via the ARC Research Hub TIDE, Main Road WA, Aimsun, the ARC CRC iMove and the Department of Infrastructure, Transport, Regional Development, Communications and the Arts.
