My research focusses on institutions in governance. With language being the central transmission belt in all matters social, I often use natural language processing (NLP) to answer my research questions. The quantitative models I apply draw from classic statistical approaches, but I also use machine learning. Recently, I have been working extensively on Latin America.


Prior to joining Cardiff as a Lecturer, I worked as a Data Scientist in industry, and also held a position as Departmental Lecturer at Oxford University. I graduated with a PhD in Political Science from the University of Mannheim.







My teaching philosophy is based on the idea of Empowerment. Every student is different and has distinct, and very personal goals and motivations. Some are looking for tools to implement change as practitioners, others are eager to develop a career as researchers or seek to grow personally.

The key to lecture such a diverse and challenging group is to involve students as much as possible. Students need to be aware that it is they themselves who are responsible to reach their own goals. In return, it is my task to direct them to the necessary tools to acquire the knowledge and skills they strive for.

By the way: I am Fellow of the Higher Education Academy in the United Kingdom.
