Research Summary

I am on a Wellcome Trust doctoral programme in neuroscience. I am interested in how the brain forms maps of the world.

Together with Tim Behrens and Jill O’Reilly, we found that the human brain navigates between abstract concepts and memories using the same grid-cell mechanism as the one used for navigation in physical space - the Stretchy Birds experiment. Here is the open-access paper and here is the Science cover written for the wider audience.
