My research interests are in the hydrology of tropical catchments, in particular the physical processes, and using hydrological models to understand and model hydrological response behaviour. My research so far has focused primarily on catchments that experience distinct seasonality in rainfall (i.e. Thailand) using a combination of fieldwork data collection and hydrological modelling.



I am currently involved in the following projects:


a) assessing the hydrological and water quality impacts of 'green technology' such as green roofs and bioretention systems.



b) my interest in floods has resulted in dating flood sediments using optically stimulated luminescence (OSL) methods to understand flood histories; flood modelling using hydraulic models and flood deposits (e.g. boulders).
