Dr Christian Arnold
Senior Lecturer in Politics
- Available for postgraduate supervision
Overview
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.

Research
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 more and more with neural networks to tackle challenges in data privacy, NLP and applied computer vision. My substantive research focuses on institutions in governance. What drives and determines the rules of political decision making?
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.
Teaching
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.
