Matilde Vaghi

Principal Investigator

Matilde is an MRC Career Development Fellow and Reader of Psychology at Birkbeck, University of London. Her lab is interested in developing novel approaches to studying brain networks and cognitive processes implicated in psychiatric disorders on the compulsivity spectrum. A key goal is to understand the brain mechanisms underlying the emergence, maintenance, and remission of psychiatric symptoms and to move to personalisation of treatments for people affected by psychiatric conditions.

Matilde gained her PhD in Experimental Psychology at the University of Cambridge under the supervision of Trevor Robbins and Ed Bullmore. Then, she was a postdoc at the Max Planck UCL Centre for Computational Psychiatry and Ageing Research and at the Wellcome Centre for Human Neuroimaging in London. Here, Matilde used publicly available datasets from the NeuroScience in Psychiatry Network and worked on understanding the developmental trajectory of cognitive processes and neural networks implicated in compulsivity with Ray Dolan. To create a tool apt for large-scale and longitudinal data collection and to engage the public in science, she also contributed to the development of a new smartphone app ‘The Happiness Project’ with Robb Rutledge. She was then awarded a Human Frontier Science Program Fellowship and a Young Investigator NARSAD Award to continue her work at Stanford with Russ Poldrack.

Dominika Varga

Postdoc

Dominika completed an integrated Master’s in Psychology at the University of York with Professor Beth Jefferies, investigating flexible semantic cognition and context-appropriate concept retrieval. She then pursued a PhD at the University of Sussex with Professor Chris Bird, examining how prior knowledge and predictions shape the processing and memory of naturalistic events. During her PhD and subsequent 1.5-year postdoc, she gained expertise in behavioural and neuroimaging methods (fMRI, fMRS) and designing innovative paradigms, including naturalistic movie-based designs, to test neurocognitive theories of learning and predictive processing. As a postdoctoral researcher in the Vaghi Lab, she is excited to develop novel tasks and apply precision functional mapping and computational modelling to examine how individual brain circuits support learning and cognitive control in psychiatric disorders.

Moritz Schepke

Master student

Moritz is a Master's student in Clinical Psychology at the Technical University of Dresden. Through his studies and internships in cognitive science labs and clinical facilities, he developed a particular interest in psychological disorders on the compulsivity spectrum. He is fascinated by cognitive modeling approaches, especially metacognitive models and sequential sampling frameworks, that help improve understanding of the cognitive processes underlying compulsive behavior. Alongside research in psychopathology, he is also interested in making mental health care more accessible by strengthening community-based approaches.

Siyuan You

Intern student

Siyuan is an undergraduate Neuroscience student at King’s College London. She developed an interest in the biological basis of behaviour in high school and has gained hands-on experience in cellular and molecular techniques through internships in labs focused on neuroimmunology and neurodegenerative diseases. In the Vaghi Lab, Siyuanhopes to further explore computational models and brain imaging in psychiatric research, and to build skills for a future PhD. Outside the lab, she enjoys hiking, climbing, crocheting, painting, and scuba diving.
