Ahmed H. Abdelrazik

PhD researcher studying how brains gather evidence, accumulate it over time, and decide when to stop, from sequential decision-making in obsessive-compulsive disorder to the dynamics of large-scale neural activity.

01 — Now

I am a PhD student in Computational Neuroscience at the University of Tübingen and the Max Planck Institute for Biological Cybernetics, supervised by Prof. Peter Dayan. I came to neuroscience from aerospace engineering and control theory, and my work lives on the bridge between the two: I use ideas from control theory and dynamical systems to understand how people make decisions, and I look for neuroscience-inspired algorithms that could, in turn, help machines act intelligently in the same uncertain world.

My first project models sequential decision-making in OCD as a Partially Observable Markov Decision Process, asking what makes evidence-gathering tip into indecision. Next, I am turning to hierarchical decision-making and meta-control (how people decompose complex tasks across levels and timescales), drawing on the theory of layered control architectures from engineering.

Information gathering in OCD during sequential decision-making

Supervised by Prof. Peter Dayan · University of Tübingen

A POMDP account of indecisiveness in obsessive-compulsive disorder. I model the ideal observer's stopping policy, then add interpretable deviations (recency, urgency, and risk) and fit them to behaviour to locate the mechanism behind excessive sampling.
