Biography

Research

I am an interdisciplinary researcher mainly working with methods from machine learning (ML) and artificial intelligence (AI). By building computational models of complex (often cognitive) phenomena I attempt to 1) better understand these phenomena, 2) provide valuable tools for domain experts and end users, and 3) improve the state of the art in ML/AI. Interpretability and robustness is crucial to gain insights and incorporate expert knowledge into the systems.

A focus of my research is on modelling musical structure and perception as a particularly rich and challenging problem. Beyond that, my research includes topics such as the dynamics of communication between agents and the formation of latent/mental representations.

More broadly, I am interested in the development and application of intelligent and autonomous systems, including their social and ethical implications as well as the resulting challenges in arts, legislation and policy making.

Short Bio

Before joining Durham University as an Assistant Professor in Computer Science, I worked as a Postdoc in the Digital and Cognitive Musicology Lab at EPFL, Switzerland (2018–2021). I did my PhD in the Machine Learning and Robotics Lab (now Learning and Intelligent Systems Lab) in Stuttgart/Berlin, Germany (2012–2017) after studying Physics and Philosophy at FU Berlin.
