I am a social neuroscientist interested in how the environments we live in shape our behavior. For example, did you know that merely viewing an alcohol advertisement can increase aggression and racism? My research attempts to understand these kinds of phenomena. So, do you act differently after consuming alcohol at home versus in the pub? Do Star Wars posters negatively impact women’s interview performance? Do recent trends towards atheism in the United Kingdom mean spiritual interventions are unappealing? Does use of the stars and stripes on beer cans increase purchasing among patriotic Americans? Stay tuned to find out!

My recent work has focused on mechanisms of self-control and stress-induced alcohol consumption, examining the role of cardiovascular responses and interventions to improve coping strategies. Other work examines alcohol intoxication and mechanisms of impulsivity, measuring cortical activity and its relation to task performance. Notably, this work is interdisciplinary, drawing from social, behavioral, health, and clinical psychology, in addition to neuroscience via the use of electrocardiography (ECG), impedance cardiography (ICG), electrodermal activity (EDA), electromyography (EMG), and electroencephalography (EEG).

My research also emphasizes the importance of equality, diversity, and inclusion (EDI). My postgraduate work with Dr Bettina Casad examined how stereotypes and sexism affect mental and physical health of women in science, technology, engineering, and mathematics (STEM). After completing my PhD, I worked as a postdoctoral research fellow for the EPSRC funded project "Inclusion Really Does Matter" led by Dr Ioana Latu. This research used virtual reality to inform development of intervention techniques to promote engagement with diversity initiatives in STEM. Current EDI work examines the impact of prejudiced large language models (e.g., ChatGPT) and extended contact to reduce prejudice against racial minorities.

I am module leader for PSY1008 (Personality and Mental Health), PSY1016 (Foundations in Social Psychology), PSY2003 (Social Psychology), and PSY3040 (Psychobiology of Drug Addiction). I have previously led PSY2021 (Introduction to Health and Addiction Science; not currently offered) and contributed to PSY3047 (The Social Psychology of Prejudice and Discrimination; not currently offered).

I supervise students for the BSc Psychology, MSc Foundations in Clinical & Health Psychology, and MRes Neuroscience programmes. I am also open to supervising MPhil and PhD students, see details here. If you would like to discuss potential supervision, feel free to send me an email so we can discuss it further.
