I am a psychologist and neuroscientist. My research uses electrical or magnetic stimulation to modify brain activity, as a way to understand how the brain controls our behaviour. I am particularly interested in the ethical limits of modifying behavour. For example, is it right to enhance brain activity when revising for an exam? I enjoy working with philosophers and legal scholars who are also interested in these questions.
When not in the lab or the office, I am a slow runner (PB 4:47) and a weak rock climber, and am regularly outsmarted by my two small daughters.
I hold a BSc in Cognitive Science from the University of Sheffield, and later completed an MSc in Cognitive Science at the University of Birmingham. I stayed on in Birmingham to complete a PhD in Psychology an 2005.
After my PhD I worked as a Departmental Lecturer in Experimental Psychology at the University of Oxford. In 2009 I moved to a research post at Bangor University, to work on an EU-funded programme to study brain stimulation and human-computer interaction.
I left Bangor in 2013 to take up a Lectureship at Swansea University, and in 2015 I moved to MMU as a Senior Lecturer.
