At the WSL since 2014:
Data scientist / system engineer (project lead for meteorology/climate observations in the long-term forest ecosystem research programme LWF; support member for various other projects such as for TreeNet, ICOS, GCOS and other projects).

Expertise

- Project management and system engineering for LWF meteorology
- Design and employment of meteorological instruments, sensors, and stations
- Automation of measurement systems (loggers, embedded systems, cameras)
- Design of solar power and battery systems for remote stations
- Maintenance/development of over 40 stations throughout Switzerland
- Processing of data with R and python on linux servers on-premise and at AWS and Azure
- DB management (relational, NoSQL), visualizations with js (amcharts, highcharts, Shiny)
- Big data processing (incl. machine learning) with Lambda, Spark, Hadoop, and Singularity

LWF Meteorology, Agrar- und Forstmeteorologen (no homepage), GCOS, ICOS, TreeNet, Swiss Society for Meteorology (SSM/SGM)

FURTHER INFORMATION

Projects

ICOS-2: Integrated Carbon Observation System in Switzerland, Phase 2017-2021

Die Forschungsstation Seehornwald Davos wurde in den 80er-Jahren von der WSL initiiert und ist damit eine der ältesten permanent betriebenen Wald-Vegetations-Forschungsstationen in der Schweiz.

TreeNet - The biological drought and growth indicator network

TreeNet ist ein internationales Beobachtungs- und Forschungsnetzwerk, in dem Punktdendrometer automatisch die täglichen Stammradiusschwankungen von Bäumen erfassen. Der kontinuierliche Fluss von Daten liefert Echtzeitinformationen über die Wasserverhältnisse im Baum und das radial Stammwachstum

FORClimateS

The project aims to aggregate and synthesize existing information on different spatial and temporal scales to provide decision-makers with relevant and robust information on short- and long-term risks for forests and forest functions and on adaptation strategies under different climate futures

PRO3FILE

To improve our assessment of ozone effects on forest ecosystems, we advocate the need (i) for further experimental and long-term monitoring studies and (ii) to develop physiological and demographic modelling tools.

Integrated Carbon Observation System (ICOS)

Integrated Carbon Observation System (ICOS) is a European research infrastructure to quantify and understand the greenhouse gas balance of the European continent and of adjacent regions.
