I am interested in understanding the mechanisms responsible for the onset and maintenance of hallucinations and delusions, especially through the use of Bayesian models of perception and cognition. Relatedly, I am interested in leveraging complex clinical psychology datasets with multiple timepoints to gain insight into the symptoms related to psychosis, and how they change over time.

Organisational, technical and scientific support for the research projects of the Clinical Psychology and Psychotherapy team. This includes procurement and maintenance of research devices, and development and maintenance of research and analysis software, either directly or in collaboration with members of the team.

My background is in cognitive/computational psychology and neuroscience, where I have explored the algorithms responsible for perceptual decisions, confidence, visual search, and context-dependent decision-making. To do this I have used a variety of computational models with a particular focus on Bayesian models of cognition. I have also explored the links between the algorithms specified by such models, and their implementation in the brain, using tools such as magnetoencephalography (MEG).

I completed my doctoral degree in Experimental Psychology with Nick Yeung and Rafal Bogacz (University of Oxford). During this time, I also conducted a research visit to the group of Wei Ji Ma (New York University). Following my doctoral degree, I worked as a research scientist in the group of Tobias Donner (UKE, Hamburg).

A full list of my publications is available on Google Scholar and on GitHub, you can find various of my code projects.
