Dr Heng Choon (Oliver) Chan
Associate Professor of Criminology
Dr Chan's research focuses on sexual homicide, sexual offending, stalking behaviour, juvenile delinquency, psycho-criminology, and Asian criminology.
We aim to understand and predict the complex causes, contexts, and broader societal impact of human behaviours, and where appropriate, how these can be improved. To do this we examine the effects of a wide range of factors, including mass media, demographics, social networks, education, psychological dispositions, and public policies.
Furthermore, we work with stakeholders in education, criminal justice, and mental health to steer our research questions and to render discoveries in social and behavioural science into advice, policy, and practice that is relevant and implementable.
Our research centres on the development and empirical testing of mechanism-based models of human behaviour. Correspondingly, we strive to inform policy, advance social-behavioural science theories, and develop and teach innovative empirical methods.
We, therefore, welcome all research and/or teaching-related collaborations that seek to employ an analytical approach to understanding human societies and behaviours.

Our research centres on the development and testing of causal mechanism-based models of human behaviour. Correspondingly, we strive to inform policy, advance social-behavioural science theories, and develop and teach innovative empirical methods.
We, therefore, welcome all research and/or teaching-related collaborations that seek to employ an analytical approach to understanding human societies and behaviours. So, if you’re interested in working with us, please feel free to contact any individual member whose name and email can be found under the People section or direct your queries to the cluster lead Dr. Rodolfo Leyva at (r.leyva@bham.ac.uk).
CCBS staff lead and teach all the research methods modules for the Department of Social Policy, Sociology, and Criminology undergraduate programmes, as well as the majority of the postgraduate research methods modules for School of Social Policy and College of Social Sciences. Moreover, we are currently developing a series of doctoral training workshops and online short courses on social network analysis, experiment design, and advanced statistical modelling.
As a collective, CCBS staff have expertise in a wide range of quantitative research methods. These include sampling methods (e.g., cell weighting, poststratification); data-collection methods (e.g., experiments, surveys), data-merging methods (e.g., record linkage, imputation); and data-analysis methods (e.g., agent-based modelling, structural equation modelling, multilevel modelling). Additionally, we also have expertise in systematic approaches to qualitative research methods such semi-structure interviews, focus groups, and thematic analysis. Said methodological skillset coupled with our interdisciplinary background enables us to advice on and/or evaluate just about any type of social or behavioural research that's interested in determining effects and causal mechanisms. More specifically, we can consult on any aspect of a research project’s design, run primary research, and/or conduct data analyses or impact evaluations.
This consultancy service is open to any public, third-sector, or private organisation, and is supported by our university’s commercial branch Birmingham Enterprise Ltd. If you’re interested in this service, please direct your queries to the cluster lead Dr. Rodolfo Leyva at (r.leyva@bham.ac.uk).
