2009 – 2013
Erwin's PhD was aimed at extending Lucy Marshall's initial work on HMEs - these wonderful models that allowed one to not make an assumption about a fixed rainfall-runoff transformation. Erwin assessed the possibility of using these models in ungauged catchments with great results. Erwin's phd was supervised by Scott Sisson in stats, and Lucy Marshall at Montana, where he ended up staying for nearly 6 months.
