Research
My PhD thesis is on the topic of improving hydrologic and hydraulic modelling. You can find detailed information about my publications, software, and other work on my CV.
Hydrologic and Hydraulic Model Development
I work with James R. Craig and Bryan A. Tolson to develop improved methods for modelling. My recent research area involves working with the blended model structure, which is available within the Raven Hydrologic Modelling Framework. My current research focuses on hydraulic modelling and floodplain mapping methods, including application of Blackbird to large-scale and real-time case studies.
