Teaching
My teaching focuses on programming with R and applied econometrics in Marketing. I aim to convey a valuable data science toolkit that enables students to answer complex economic or business questions with data and statistics.
To convey the—sometimes technical and challenging—programming and statistical methods, I follow a teaching philosophy that avoids teacher’s monologues in lengthy lectures but instead forces students to get their hands dirty quickly and learn by doing. Hence, my courses involve short primers on technical concepts but heavily rely on the students working in small groups to solve small case studies. From my experience, students learn (sometimes challenging) topics such as programming and statistics in a more motivating and effective way.

Course Objective
Most academic fields require proficiency in at least one data-centered analysis tool. For many, the R programming language has become the tool of choice. However, the first steps in coding can be intimidating and discouraging—primarily if you have never worked with a programming language before. This course aims at providing a results-oriented, applied, and hands-on introduction to the essential parts of a Data Science project in R. We will introduce the libraries and frameworks necessary for your analysis and focus on teaching you the implementation and application of those tools. We’ll present small examples throughout the lecture and provide you with application exercises that you can work on for yourself.
Our goal is to show you the scope of possibilities within R and leave you with the impression that you can confidently implement your empirical projects in R. We will focus on the Tidyverse ecosystem, a consistent and intuitive framework for building your data analysis from start to finish. After completing this course, you know how to apply the essential Tidyverse tools for everyday Data Science tasks in R—primarily data wrangling, data visualization, and communicating results.
Course Description
We aim this course at beginners who are either entirely new to R as a programming language and/or want to learn about the Tidyverse ecosystem. The course covers four primary areas of the typical data science process and introduces the respective tidyverse tools:
- Plotting with
ggplot2 - Data wrangling with
dplyr - Communicating your results with R Markdown
- Regressions with
tidymodels
We will not cover statistical or theoretical concepts in this course, as the focus will lie on applied coding.
Methods
We will let you eat cake first. What does that mean? Many programming courses start with the absolute basics — variable types, syntax, loops, etc. Those are important but quite dull in the beginning. Instead of monotonously walking you through those, we follow a different teaching philosophy.
Each topic will start with a very friendly and sometimes a bit complicated cake. And you will dive right into it by executing and adapting the code for that “data science cake.”
For example, we will show you an advanced visualization right at the beginning of the course and focus on what is possible eventually. While this might appear intimidating at first (“how should I ever be able to code that from scratch?”), we will walk you through the steps and introduce the methods to get there during the course.
The course will alternate between short introductions to a concept or method and small do-it-yourself coding exercises. In between the three sessions, you are encouraged to work on provided exercises that further deepen your understanding.

Course Description
This course teaches around 200 students per semester the basics of data analysis with the software R. We aim to enable the students with a valuable toolkit to answer data-driven economic questions with a modern Data Science toolkit. The course follows the Flipped Classroom principle.
We provide the course content in videos “on-demand” before the face-to-face classroom session. Students watch the videos before coming to class and hence learn theoretical concepts. We then build upon that foundation and use the face-to-face time in class to deepen students’ understanding. In particular, we fully allocate the time in class for interaction in the form of small 60-minutes hands-on data science exercises in small groups and effective Q&A sessions.
TechAcademy
At TechAcademy, we teach coding in Data Science with R and Python, Web Development, and App Development to university students from all fields and previous experiences. We do so using an innovative blended learning approach that combines e-learning courses with offline Coding Meetups, group projects, a strong community, and individualized support from mentors.
Before joining the executive board of the non-profit organization, I led the organization’s data science and learning development team. Together with that team, we developed the innovative learning concept that significantly lowers the entry barrier to coding education and opens once closed (career) opportunities for students—especially from fields other than computer science.
