Research

My PhD thesis is on the topic of hydrologic model identifiability. You can find detailed information about my publications, software, and other work on my CV.

Hydrologic Modelling and Calibration

I work with James R. Craig and Bryan A. Tolson to develop improved methods for hydrological modelling. My current research area involves working with the blended model structure, introduced by Mai et. al. (2020) and available within the Raven Hydrologic Modelling Framework.
