I am currently working as a researcher in computational psychiatry at the Ilab where I develop nonparametric Bayesian models of delusions.

Previously, I was working as a postdoctoral fellow in the Embodied Computation Group at Aarhus University where I studied cardiac interoception using computational modelling, brain imaging and physiological signal analysis.

I am the creator and maintainer of the following Python libraries:

• pyhgf - A JAX implementation of the generalized and nodalized Hierarchical Gaussian filter.
• Systole - a package centred on processing and visualization of ECG, PPG and respiratory signals.
• The Cardioception Toolbox - a psychophysics experiment to measure and analyze cardiac interoceptive beliefs (see also the method paper)
• metadPy - a package to compute a variety of metacognitive efficiency parameters from trial-level confidence ratings (SDT, meta-d using MLE and Bayesian methods).
