Biography

Ines studied Biochemistry at the University of Coimbra in Portugal. Her interest in studying the brain started as a BSc student, when she spent one year doing research at the Biomedical Research Institute “Alberto Sols” in Madrid, Spain, as an Erasmus student. Ines received her doctoral degree from the University of Coimbra in 2012. She was awarded a Sir Henry Wellcome Fellowship in 2013 and moved to London to perform her research project at Imperial College London and University College London. In 2017, she joined Surrey as a Lecturer in Psychological Neuroscience.

Research Interests

My research focuses on understanding the role of brain networks on cognitive functions and the use of brain stimulation as a neuromodulator. My research combines functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to understand how brain stimulation (TMS, tACS, tDCS) can be used to modulate brain dynamics and behavioural performance. I am interested in how brain oscillations mediate long-range connectivity and particularly how neurostimulation can be used to improve network communication following brain injury. 

A second strand of research that started during my PhD, has been focused on understanding the neurobiological basis of the cognitive deficits in neurodevelopmental disorders, particularly Neurofibromatosis type 1 (NF1). My research in this field is characterized by being interdisciplinary and translational, applying neuroimaging and neurophysiological techniques to translate the inhibitory hypothesis in NF1. I have used spectroscopy, molecular imaging and magnetic resonance imaging to provide a comprehensive understanding of the pathophysiological alterations present in NF1.
