Current research interests and projects focus on:

Smoking-related biomarkers

- impact of biomarker feedback on cognitive antecedents of behaviour change

- feasibility of using biomarker feedback to motivate cessation

Smoking-related diseases

- detection of cardiovascular and respiratory diseases at population level

- inter-relationship between disease diagnosis and smoking status

Tobacco product regulation

- evaluation of smoke constituent testing regimes

- level of exposure of smokers of different tobacco products to carcinogens

- association between tobacco product design and smoke exposure

Tobacco control policy

- evaluation of legislative changes on use of nicotine replacement therapy

- assessment of attitudes in the general population towards new tobacco control strategies

Novel smoking cessation interventions

- development and testing of pharmacological and behavioural treatment for smoking cessation

- systematic meta-analytic evaluation of novel interventions

Smoking and mental health

- association of happiness with smoking and smoking cessation

- changes in mental health (anxiety, depression) as a function of changes in smoking status


- evaluation of smoking-related health education in the medical profession

- early changes in synaptic transmission and plasticity in Alzheimer's Disease

- classification of Behaviour Change Techniques (BCTs) in health behaviour interventions

Research activities involve a variety of techniques/methods used in both human (randomised controlled trials, epidemiological analysis, laboratory/experimental work) and animal studies (electrophysiology).

Lion Shahab is an Associate Professor  in Health Psychology. After graduating from the University of Oxford in psychology, philosophy and physiology in 2003, he gained an MRC-funded masters in health psychology from the Institute of Psychiatry in 2004 and went on to complete an MRC-funded PhD in 2008 on the role of smoking-related biomarkers in smoking cessation under the supervision of Professor Robert West at UCL. While working as a research associate in the Health Behaviour Research Centre, he also completed a masters in neuroscience and gained his Stage II training qualification in health psychology at UCL under the supervision of Professor Susan Michie. In 2011 he took up a lectureship in health psychology and continues his research into different aspects of tobacco use, more recently expanding into other health behaviours and mouse models of Alzheimer's disease.
