Overview

I am a computational hydrologist using large samples (hundreds to thousands) of catchments and modular modelling frameworks to gain new insights into hydrological processes and climate change impacts. I co-produced the CAMELS attributes data set, I am further developing the suite of hydrological models FUSE and I am the Chair of the Panta Rhei working group on large-sample hydrology.

I am an Honorary Research Fellow at the University Exeter and, since January 2022, a Senior Hydrologist at Fathom. I previously worked as a Hydrologist at the Environment Agency and as a Postdoc at the University of East Anglia in Norwich, UK and at the National Center for Atmospheric Research in Boulder, USA. I hold a PhD from the University of Zurich and a Master's from ETH Zurich in Switzerland.

For publications and further details, please see my CVResearchGate and Google Scholar.

Broad research specialisms: 

Hydrology, climate change impacts, data science, community models, uncertainty assessments, adaptation to climate change

Qualifications

PhD Physical Geography (University of Zurich, Switzerland)
MSc Environmental Sciences (ETH Zurich, Switzerland)
BSc Environmental Sciences and Engineering (EPFL, Switzerland)
