About us

We are a part of the Hydrology and Climate group (H2K) within the Department of Geography at the University of Zurich.

PhD students

Simon Etter

I am a PhD Student at the University of Zurich and I started working on the CrowdWater Project in April 2016. I already did my Master’s Degree in Zurich. I hope to find new types of hydrological data collection methods based on citizen science from which everyone can benefit in the end. Furthermore I hope that our strategy will be applicable not only to Switzerland but for the entire world.


Barbara Strobl

I am a PhD student at the University of Zurich and I started working on the CrowdWater project in April 2016. I come from Austria and did my previous studies at the Karl-Franzens University in Graz and at the University of Natural Resources and Life Sciences in Vienna. I hope that with the help of “the crowd” we will be able to improve our understanding of hydrological processes and through that also hydrological forecast models.


Milena Mächler

As a master student in physical geography at the University of Zurich I work in the project CrowdWater. I am particularly interested in the inclusion of young people in the project because I am convinced that active participation in a research project increases the understanding of (hydrological) processes. Thereby we can also increase the interest in the important and contemporary topic of water.


Prof. Dr. Jan Seibert

As a hydrologist I am curious about water. Current research topics include the use of catchment models for land-use and climate change impact studies, runoff generation processes and their representation in models, the value of different types of data and uncertainty analysis. Today’s mobile devices provide exciting opportunities to include the public in hydrological observations.


Dr. Ilja van Meerveld

I am a researcher at the University of Zurich. My research focuses mainly on understanding hydrological processes. I have been involved in field-studies in a range of places (Canada, USA, Alps, Madagascar, Philippines) and am interested in citizen science in hydrology because it provides new opportunities to obtain hydrological data and knowledge, and allows us to study previously unmonitored areas.


Dr. Tracy Ewen

I am a climate scientist by training, and am passionate about the communication of science and making scientific (climate) information more accessible to the public (which I help do at climatiq.ch). I was involved in an early version of the project data.rescue@home, in which student volunteers digitized historical weather data from all over the globe, resulting in a valuable upper air data set for climate analysis (Stickler et al., 2010). I am also interested in learning and teaching about water resources through gamification and game play (Ewen and Seibert, 2016), and contribute (as a citizen scientist) to OpenNature.
