About Me

I am a graduated computational ecologist by training and an independent data visualization specialist/designer by heart with extensive hypothesis-driven research experience and strong skills in data wrangling, statistical analysis, model development, and data visualization.

I have created visualizations across all disciplines, purposes, and styles and regularly teach data visualization principles as well as basic and advanced ggplot2 techniques.

Data Visualization

I have been working as an independent data visualization specialist since the beginning of 2020. Since then I have worked for a large number of clients as a designer, consultant, analyst, and workshop instructor in the field of data visualization and reproducible analysis. I am constantly strengthening my skills in design and have built a diverse portfolio covering a wide range of topics, chart types, purposes, and tools by contributing to self-led personal projects and numerous data visualization challenges such as TidyTuesday, #30DayMapChallenge, and #30DayChartChallenge.

Computational Ecology

I am working as a scientific researcher (PostDoc) in the Department “Ecological Dynamics” at the Leibniz Institute for Zoo and Wildlife Research (IZW) in Berlin, Germany. As a computational scientist, I apply analytic and mechanistic modeling approaches to answer questions related to the movement ecology of animals and the dynamics of populations, communities and diseases in space and time. In 2019, I was awarded a Ph.D. degree in Ecology (Dr. rer. nat.) at the University of Potsdam as part of the BioMove research training group.

My favorite tool for all data-related tasks is R, an open source and highly extensible language for statistical computing and graphics techniques. To visualize data I mainly utilize the package {ggplot2} from the {tidyverse} package collection including many more that I use on a daily basis for all kinds of data preparation and analysis. More recently, I find myself enjoying a lot using other, non-programing design and charting tools such as Figma, DataWrapper, and Flourish.
