Pascal Emanuel Egli
Om
Pascal Egli has a PhD in Geography from the University of Lausanne, Switzerland ("ice-marginal subglacial channels and their relationship to the rapid retreat of temperate Alpine glaciers", 2022), and a Master degree from ETH Zurich (2014), on the topic of Large Eddy Simulations for urban canopies. He has work experience in natural hazards engineering, including hydraulic modelling in 1D and 2D.
Pascal has done glaciology fieldwork on several Alpine glaciers in the Swiss Alps, on Norwegian glaciers, on outlet glaciers of the Northern Patagonian Ice Sheet in Chile, on surge-type glaciers in Pakistan, on natural hazards in Uganda as well as in the Nepal Himalayas, using methods such as Ground Penetrating Radar, hot water drilling, UAV photogrammetry, tracer experiments, installation of sensors and meteo stations, and dGPS.
Forskning
I am currently implied in several research projects.
(1) I am a contributor to the GOTHECA project (2021-2025). GOTHECA focuses on glacier impacts on hydrological catchments in Europe, Central Asia and South America. The objective is to gain a better understanding of glacier hydrology and future water resources, as well as of the hydrological dangers posed by GLOFS. I am responsible for the fieldwork component of GOTHECA, and I am contributing to writing publications.
(2) I am the PI at NTNU for the new EU Horizon project "CryoSCOPE" (2025-2029), focusing on permafrost, snow and glaciers in Europe and in the Indian Himalayas. The NTNU part of the project investigates climate change impacts on retreating glaciers in Norway and Switzerland, and implications for hazards such as outburst floods and droughts. A new combination of glacier models will be tested and validated with extensive field data. The human Geography part of the project focuses on the perception and preparedness in society.
(3) I am the local co-PI at NTNU for the new project RETRACE (2024-2027): ResilienceS to climate risks: lessons from Arctic and Pacific communities. The three-year project responds to the increasing impact of natural disasters on over 2.3 billion people since the beginning of the millennium. It has a particular focus on Arctic and Pacific communities vulnerable to climate risks.
(4) Changing Landscapes (2023-2026): A project led by Dr. Iñigo Irarrazaval from CIEP in Coyhaique, Chile, by Prof. Marcelo Somos-Valenzuela from Universidad de la Frontera, Temuco, Chile, and by Dr. Inés Dussaillant from the World Glacier Monitoring Service at the University of Zurich, Switzerland. This project focuses on rapid changes of the outlet glaciers of the Northern Patagonian Ice Sheet and their interactions with proglacial lakes.
(5) Threatened Lifelines (2024-2028). Analyzing and managing the impacts of shrinking glaciers on water flows, land use, and livelihoods in mountain communities of the Indian Himalayas. This is project is led by Martin Lukas at IGE, with a collaboration with Oddbjørn Bruland from Civil Engineering (snow hydrological modelling and hydropower) at NTNU. It has received seed funding from the NTNU focus area "community" and two PhD positions starting in autumn 2025.
(6) MERIT project (2022-2026), East Africa: Ethiopia, Uganda and Tanzania. Capacity building on managing natural hazards.
(7) My personal research project is a continuation of my PhD research and it focuses on glacier collapse features. Collapse features occur close to the snout of temperate alpine glaciers due to the internal erosion and melt-out of subglacial channels. Now the objective is to better understand the processes and to obtain a more systematic assessment of the spatial distribution of collapse features.
