I am a geoscientist with over 10 years of interdisciplinary experience working across research institutions, international organistations and multilateral donor projects. My main interest is on high mountain processes related to natural hazards, water resources and resulting impacts upon communities. I use and develop geoscientific models and other datascience tools in combination with field campaigns to understand these processes and improve mapping and forecasting methods.
