Dr Nans Addor

Nans is the Principal Hydrologist at Fathom. He explores how catchments store and release water, how they behave during extreme hydroclimatic events and how this leads to river flooding. Climate change is already impacting river flows and Nans uses a combination of climate and hydrological models to anticipate future changes and quantify their uncertainties.

Open hydrology is a passion of Nans’. He co-led the production of CAMELS, an open dataset covering hundreds of US catchments that is now widely used in both academia and the industry. CAMELS paved the way for similar datasets around the globe and for a global community dataset and cloud-based platform, Caravan, developed with partners from Google and academia. 

In the past, Nans worked at the Environment Agency and as a contractor for UK water companies. He holds a PhD from the University of Zurich and a Master’s from ETH Zurich in Switzerland. He was a postdoc at the Universities of Exeter and East Anglia, and at the National Center for Atmospheric Research in Boulder, USA. He maintains strong links with academia to ensure that Fathom products are underpinned by cutting-edge science, and he draws from his industry experience to deliver products that meet clients’ needs.

After studying and working in multiple countries, Nans brings a unique perspective to Fathom. But with a passion for modeling, data visualization and open science, he fits right into the team.  

When he’s not working, Nans can be found cooking up a storm in the kitchen and exploring the great outdoors with his family.
