Projects & Publications
The goal of my work is to use all data available to the modern neuroscience lab to uncover the mysteries of complex thought and translate our findings into more powerful artificial agents. My empirical work is currently mostly based on neuroimaging data of the developing brain, large scale data of human decision making and single cell recordings in non-human primates. My modelling work currently focuses on artificial neural network models, using a combination of supervised training, reinforcement learning, and biologically inspired wiring rules.
Ongoing
We recently introduced the new spatially-embedded Recurrent Neural Network model which can recapitulate numerous neuroscientific findings, from large scale connectome structure down to functional codes used by single neurons. We are in the process of expanding this model with further biophysical constrains and a theoretical analysis of dynamics for optimising network communication.

No preprint expected until 2023. Get in touch if you want to know more.
General generative AI: Together with the Cognitive AI Lab at Intel Labs I am working on methods to improve generative AI agents to develop their problem general problem solving skills. You can find more details on our ideas on the website of the AAAI workshop we are working on.
