Dr Christian Arnold

Senior Lecturer in Politics

School of Law and Politics

Available for postgraduate supervision


Using data driven methods from statistics and machine learning, my work lies at the intersection between social science and computer science.

Recently, I have been working quite a bit with neural networks to study data privacy and institutions in governance. Some of my projects have had a particular focus on Latin America.

You can read my Political Science papers in the Journal of Politics or International Interactions, among others. I presented findings relevant to Computer Science at the International Conference on Machine Learning and the Theory and Practice of Differential Privacy Workshop Series.

I regularly collaborate with private and public institutions as a consultant.


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.
