The main focus of my research is on the meaning of functional brain imaging signals: what do they tell us about brain activity and how might we best use this information to improve our understanding of normal brain function and neurological diseases? I use a range of in-vivo techniques in order to uncover the neurophysiological basis of neuroimaging signals and the mechanisms of neurovascular coupling that underlie them. I am also interested in science communication, in particular the communication of brain imaging research findings beyond academic audiences and the impact of this upon public understanding of neuroscience.
Current projects in my lab are focusing on:
- The roles of the neurotransmitters dopamine, serotonin and acetylcholine in modulating neuroimaging signals and neurovascular coupling.
- The neuronal and neurovascular effects of transcranial direct current stimulation.
- The impact of system inflammation on neurovascular coupling.

Dr Aisling Spain: Aisling’s research is funded by a Wellcome Trust Research Project Grant and focuses on how alterations in the functioning of the serotonin neurotransmitter system in the brain affect functional brain imaging signals and their relationship to neuronal activity.
Miss Elizabeth Kirkham: Lizzy's research is funded by the British Academy and investigates how neuroscience can improve the effectiveness of behaviour change interventions (with respect to both intervention design and evaluation) with a specific focus on interventions to tackle obesity.
Melissa Maczka: University of Oxford Doctoral Training Centre Student on the Life Sciences Interface Program. Melissa’s project involves developing new mathematical tools to help us understand what functional brain imaging signals tell us about the activity of neurons in the brain. Jointly supervised by Dr Jonathan Marchini (Statistics, University of Oxford) and Dr Mark Woolrich (Department of Psychiatry, University of Oxford).
Gaia Brezzo: Department of Psychology PhD Teaching Fellowship. Gaia is investigating how neurodegenerative brain disease alters the relationship between neuronal activity and blood flow in the brain. This will improve our understanding of how to best use functional brain imaging tools in clinical populations as well as providing insights into the role of neurovascular mechanisms in disease progression.
Anka Gorgiev: South Eastern European Research Centre PhD Studentship in collaboration with The University of Sheffield and City College (International Faculty of The University of Sheffield), Thessolaniki, Greece. Anka's PhD in in the area of Neuromarketing and specifically addresses the issue of whether or not emerging technologies and theoretical developments in neuroscience are driving a 'paradigm shift' in marketing.
