Alexandra Diehl, PhD


University of Zurich
DSI Fellow

GI Mitglied  (

Die Gesellschaft für Informatik e.V. (GI) ist die größte und wichtigste Fachgesellschaft für Informatik im deutschsprachigen Raum.

I am a computer scientist dedicated to Data Visualization. Through the years, while I strengthened my research on visual analytics,  geospatial visual analytics, predictive analytics, and data science, I have also been interested in how can we use these technologies for the good of society and nature.

My recent efforts on this area can be found here:, and a list of my publications here.


I am also interested in environmental science, and animal protection activities, and I am a proud member of the Zurich Bird Protection / BirdLife Zurich and the Swiss Bird Protection / BirdLife Switzerland, 

and the green team of volunteers at ZÜRCHER TIERSCHUTZ.

We are working on the understanding of visualization guidelines based on the principles of Grounded Theory. Please access our preprints here:

Studying visualization guidelines according to grounded theory.

Characterizing Grounded Theory Approaches in Visualization

At the same time, we are running a community project,, for the discussion, critique, and curation of visualization concepts and guidelines.

Geospatial visual analytics applied to weather forecasting presents several challenges. Forecasters need to analyze forecasts and make quick decisions on forecasts on a daily basis to avoid, prevent, and alert society about potential hazards.

During the last years, I have been working very closely with meteorologists to develop efficient visual analytics tasks that can help them to make rapid decisions. Some of the efforts on short-term and probabilistic forecasting are already published, and others are ongoing projects, such as the case of Visual Analytics for Nowcasting.


 One of the next big scientific challenges that I want to tackle is how to process and make use of citizen data, which are heterogeneous, vague, and noisy, but yet a very valuable source of information. In particular, a big challenge that I want to tackle is the research and development of tools to help in the understanding and quantification of the uncertainty of citizen data, for the particular use in scientific models coming from meteorology.

During my ten years working in academia, I have had the honor to collaborate with colleagues from different continents and areas of expertise. Here there are some very nice pictures, some of their names are on my publications, and all of their names are deeply written in my heart.
