Psychiatry resident at Ondokuz Mayıs University, Samsun. I design measurement instruments together with engineering collaborators, build the software and models that run on them, and use both to ask how the brain decides what to believe.

Whether delusions track a failure of belief revision, a failure to attenuate self-generated sensation, or both. Beads task modelled with the Hierarchical Gaussian Filter, alongside a force-matching task run on a device built for the study. Supervised by Prof. Dr. Gökhan Sarısoy; registration pending.
In design · protocol
Akathisia treated as an attempt to make the world fit the model, rather than the model fit the world. Aripiprazole is the instrument here: if dopamine encodes the precision of prediction errors, a D2 partial agonist should act less like a dial and more like a clamp on that precision, rather than simply lowering it.
In collection
Separating fatigue from depression in MS by modelling effort-based decisions, in collaboration with the Department of Neurology.
