José M. Fernández-Fernández - Spain

José M. is a PhD Geography student at the Complutense University of Madrid (Spain). Since he was a child he knew that he would study something directly linked to maps. So he studied BSc in Geography, and then a Master’s in Geographical Information Technologies. His research within the High Mountain Physical Geography (GFAM) research group aims to develop a multidisciplinar methodology to use glaciers as indicators of climatic change (extant glaciers) and as proxies of palaeoclimatic information (palaeoglaciers), at decadal-to-millennial timescales. An important part of his research is focused on applying detailed geomorphological mapping (over extant and palaeo- glaciers, rock glaciers and debris-covered glaciers), physical-based rheological numerical models (ice perfect plasticity) to achieve palaeoglacier reconstructions, and the application of glacier-climate models to approach to palaeoenvironmental situations. The physical and chemical lab procedures for rock sample processing for the further application of cosmic-ray exposure dating (10Be, 36Cl) is also a cornerstone for the timing of climatic events with special impact on non-extant mountain glaciers.


Roxanne Frappier - Canada

Roxanne is a PhD student at the Department of Geography, Environment and Geomatics at the University of Ottawa (Ontario, Canada), interested in ice-rich permafrost. Her research falls within the context of the ongoing climate warming and focuses on its effects on permafrost. Degradation of permafrost terrain can lead to the formation of thermokarst landscapes, which have important impacts on ecosystems, biotas, snow depth, slope stability, soil strength, and infrastructures. Her main research goal is to describe and predict the extent of permafrost degradation and its effects on the landscape in response to environmental and climatic changes. She has been involved in PYRN-NA, the north american branch of PYRN, since October 2017 and is now also PYRN's canadian national representative.

Matthias Winkel copy

Matthias Winkel - Germany

Matthias is a former PostDoc of the section Geomicrobiology in the GFZ, German Research Centre for Geosciences and worked for four years in the Young Investigator Group under the supervision of Susanne Liebner. During his last year he got a subaward from the University of Fairbanks Alaska and joined a project lead by Katey Walter Anthony, Anna Liljedahl, Ronald D. Daanen, Vladimir Romanovsky and David Barnes. He worked/ still working on deep permafrost thaw environments such as submarine permafrost, thermokarst lakes and try to understand the organic matter degradation and greenhouse gas production as well as the mitigation of the gases (anaerobic oxidation of methane). Since these environments are chronosequences that thaw over long timescales these are perfect examples of how the microbial community will evolve in a globally changing climate. He is also working on active layer microbial communities in permafrost-affected peatlands and the influence of hydrology due to climate warming. He mainly uses molecular tools to characterize the microorganisms, analyze the biogeochemical background, use stable isotopes to understand specific processes and made my first steps into modelling. Now he moved to the section Interface Geochemistry and will mainly be working on snow and ice algae. He will try to understand the adaptation in these harsh ecosystems and will focus on the genomic repertoire of the algae.


Samuel Weber - Switzerland

Samuel Weber research interest concerns heterogeneous environments and climate change, especially process understanding and quantification of phenomena in mountain permafrost related to climate. His vision is to investigate fracture kinematics, to improve the understanding of processes in mountain permafrost using geophysical methods, to detect rupture processes in instable rock masses, assess rupture imminence and to design an early warning system for rock instabilities. For this, the combination of geo-science and engineering is very useful and enables field measurements at locations in hardly accessible environments. He greatly enjoy doing field work in alpine environments and being able to combine my knowledge as well as his experience with my alpine skills.
