Jessica is a cognitive neuroscientist investigating the brain networks that underlie how we perceive threats and make decisions. She is currently working as a postdoctoral research fellow at the Max Planck UCL Centre for Computational Psychiatry and Ageing Research in London, under the supervision of Professor Ray Dolan. Jessica uses a combination of computational modelling and magnetoencephalography (MEG) to determine how positive and negative scenarios are rapidly played out in the brain. She is interested in relating this to individual differences in trait anxiety.
Before moving to the UK, Jessica studied a Bachelor of Psychological Science at the University of Queensland, Australia. After being awarded Honours Class I, Jessica embarked on a PhD at the affiliated Queensland Brain Institute. Here, she was supervised by Associate Professor Marta Garrido and Professor Jason Mattingley. Jessica gained expertise in electroencephalography (EEG), MEG, fMRI, and diffusion MRI tractography analyses. She explored the anatomy and function of fast pathways to the amygdala that carry visual information about threats.
Jessica's academic publications can be found online. The data and analysis code from her first-authored experiments are also freely available. Jessica is passionate about using game-like experiments to study human behaviour, online and in the lab, and creates video games in her spare time. She is also an avid musician, which drives her curiosity about emotion in the brain.

This repository contains the code used to run and analyse an experiment, currently in progress. In this experiment, participants memorised different sequences of images, each with their own point value. Participants then play a game where they must choose between a risky and safe option, aiming to maximise the number of points gained each time.
Conscious Perception Experiment
This repository contains the code used to run and analyse an experiment, currently written up as a preprint. In this experiment, participants we used continuous flash suppression (a mirror technique that makes stimuli invisible) to see whether surprising neutral or surprising fearful faces broke into conscious perception faster.
This repository contains the code used to analyse data from the Human Connectome Project, the results of which were published in eLife in 2019. We reconstructed white matter tracts from the brainstem to the thalamus, and from the thalamus to the amygdala. We found that people with stronger fibre density along these tracts were better at recognising fearful faces and had stronger forward-flowing neural activity.
