I am a DPhil student supervised by Kia Nobre and Mark Stokes, and I am funded by a ESRC Grand Union & Scatcherd European Scholarship.
Our visual experiences are shaped by incoming sensory information and our expectations, by task-relevance, and by selective attention. We perceive the world through tainted glasses that only show us a selective and biased view of the world. My research focuses on how top-down control modulates visual perception. In my research I use functional magnetic resonance imaging (fMRI) as well as neurophysiological tools such as electroencephalography (EEG) and magnetoencephalography (MEG). Using neurocomputational modelling I aim to characterise the underlying neural methods and advance the field of visual cognition.
Currently, I am working on a project that investigates how selective attention for features and objects modulates perceptual representations during working memory maintenance. This project consists of two parts. Firstly, I will use electrophysiological methods to understand the temporal dynamics of this process. Secondly, I will use fMRI to map out visual and parietal regions to subsequently investigate how different stages of the visual hierarchy are involved in this task.
Understanding the fundamental neural processes of top-down control in perception can advance our basic understanding of how the brain processes information. In addition, this research is highly relevant to translational research in, for example, autism and schizophrenia.
I completed my undergraduate in Psychobiology and my Master's programme in Brain and Cognitive Sciences at the University of Amsterdam. However, I did not spent much time in Amsterdam as I went on to join Kia Nobre’s lab in Oxford over the final year of my Undergraduate degree and I completed two one-year research projects at the Donders Centre for Cognitive Neuroimaging (the Netherlands), and Princeton University (United States of America) during my Master’s.
