My work, my path, and how I came to study gambling as a public health issue

I am a social scientist working in the field of gambling research, policy, and public health. My academic and professional path has been shaped by one core question: how do gambling systems, products, and environments create harm, and how can societies reduce that harm in fair and evidence-based ways?

Over the years, my work has moved across disciplines, institutions, and policy environments, but it has remained grounded in population-level evidence, social justice, and the belief that gambling-related harm is not simply an individual failing. It is a structural, measurable, and preventable public health issue.

Early academic interests and foundations

My background is in social research, with a strong methodological focus on large-scale surveys, population data, and behavioural patterns. From the earliest stages of my career, I was interested in how social environments shape health outcomes, and how policy decisions often rely on imperfect or selectively interpreted evidence.

Before gambling became my primary research focus, I worked extensively with national datasets covering health, wellbeing, and social participation. This period was formative. It taught me how critical measurement design is: what we choose to measure, how we define categories, and which groups we include or exclude can fundamentally alter the conclusions drawn from data.

Those early years shaped my later approach to gambling research. I learned to be cautious of simplistic indicators, headline prevalence figures, and binary classifications that fail to capture lived experience.

Working with population surveys and national data

A substantial part of my career has involved designing, analysing, and interpreting nationally representative surveys. This includes work connected to major health and social research programmes in Great Britain.

Through this work, I became increasingly involved in gambling data, particularly large-scale prevalence surveys. These datasets are powerful, but they also come with limitations. They often focus narrowly on problem gambling screens, while missing broader forms of harm experienced by families, communities, and individuals who may not meet clinical thresholds.

This tension between what is measured and what is experienced became one of the central themes of my work.

Leadership at NatCen Social Research

For more than a decade, I worked at NatCen Social Research, where I eventually served as a Research Director. During this period, I led and contributed to a wide range of gambling studies, including national surveys, policy evaluations, and thematic research projects.

NatCen was an important environment for me. It sits at the interface between academia, government, and public debate. The work produced there is expected to be methodologically robust, politically neutral, and directly usable by policymakers.

It was also during this time that I began to see, very clearly, how evidence can be selectively used in gambling debates. I observed how industry narratives, regulatory priorities, and political sensitivities could influence which findings were amplified and which were quietly ignored.

This experience strengthened my commitment to transparency, methodological clarity, and public-interest research.

Moving toward a public health framing of gambling

As my work progressed, it became increasingly clear to me that treating gambling harm purely as an issue of individual pathology was inadequate.

Most people who experience gambling-related harm do not meet diagnostic criteria for gambling disorder. Harm often appears earlier and more diffusely: financial stress, relationship conflict, mental health strain, reduced productivity, and intergenerational impacts.

This led me to adopt and advocate for a public health approach to gambling. In this framing, gambling is understood as a health-harming commodity, shaped by availability, product design, marketing, and regulatory environments.

This perspective does not deny personal agency, but it recognises that individual choices are made within systems that actively encourage consumption and risk.

Selected Publications and Research Outputs

Closing perspective

My work has always been motivated by a simple concern: who benefits from gambling systems, and who pays the price?

By grounding gambling research in public health, social justice, and rigorous evidence, I hope to contribute to policies that reduce harm, protect vulnerable groups, and create a more balanced conversation about gambling in society.

How my research engages with policy, regulation, and public debate

A defining feature of my work has always been its close connection to policy and regulation. I do not see gambling research as something that should exist solely within academic journals. From the beginning, I have been interested in how evidence travels beyond academia—how it is interpreted, reshaped, or sometimes resisted once it enters regulatory and political spaces.

Working at the intersection of research and policy has given me a clear view of how contested gambling evidence can be. Gambling is an industry with significant economic interests, strong lobbying capacity, and deeply embedded cultural narratives around personal responsibility and choice. In this environment, research findings do not speak for themselves. They are debated, reframed, and occasionally dismissed.

One of my ongoing concerns has been the selective use of evidence. Data highlighting economic benefits or low prevalence of diagnosed gambling disorder is often amplified, while evidence about harm distribution, product risk, or long-term social costs receives less attention. This imbalance reinforces narrow policy responses focused on individual behaviour rather than structural change.

My involvement in advisory and regulatory contexts has reinforced the importance of independent research. Effective regulation depends on data that is transparent, methodologically sound, and insulated from commercial influence. Without this independence, public trust in both research and regulation erodes.

Another area where my work intersects with policy is the evaluation of so-called “safer gambling” measures. Many interventions are introduced with limited empirical testing and are later presented as evidence of responsibility or compliance. I have consistently argued that harm-prevention tools must be evaluated not only for uptake, but for actual effectiveness in reducing harm across populations.

This includes questioning assumptions about voluntary tools, information-based interventions, and consumer self-management. While these approaches may benefit some individuals, they are insufficient on their own. A public health perspective requires attention to product design, affordability, availability, and marketing exposure.

Public debate around gambling often becomes polarised. On one side, gambling is framed as entertainment and consumer choice. On the other, it is presented exclusively through the lens of addiction. My work seeks to move beyond this binary by focusing on gradients of risk and harm. Most gambling-related harm occurs among people who do not identify as “addicted” but who nevertheless experience cumulative negative impacts.

This perspective is sometimes uncomfortable for policymakers and industry alike, because it challenges the idea that harm can be neatly contained within a small, identifiable group. It suggests instead that prevention must operate upstream and at scale.

Engaging in public debate also means communicating research responsibly. I place strong emphasis on clarity, proportionality, and honesty about uncertainty. Oversimplification may attract attention, but it rarely leads to better policy.

Ultimately, I see my role as contributing evidence that enables more balanced and accountable decision-making. Gambling regulation is not simply a technical exercise; it reflects societal values about health, inequality, and the limits of commercial freedom. Research has a responsibility to inform those values, not just measure outcomes.

Industry influence, data access, and the future direction of gambling research

One of the most challenging aspects of gambling research is navigating the relationship between evidence, industry power, and access to data. Gambling is a highly commercialised sector, and much of the most detailed behavioural data is held by private operators rather than public institutions. This creates a fundamental imbalance between those who design and profit from gambling products and those tasked with assessing their impact on society.

Throughout my career, I have been cautious about the role of industry-funded research. While funding itself is not inherently problematic, the conditions attached to it often are. These can include restrictions on publication, limited access to raw data, narrow research questions, or subtle pressures to frame findings in ways that minimise perceived harm. Such constraints undermine the independence that is essential for credible public-interest research.

Access to high-quality data remains one of the central structural problems in the field. Regulators and researchers are frequently expected to assess harm without full visibility of product design, algorithmic features, or real-time behavioural patterns. In contrast, operators routinely use granular data to optimise engagement and consumption. This asymmetry limits the ability of independent research to keep pace with rapidly evolving gambling technologies.

I have consistently argued that meaningful regulation requires mandatory data sharing frameworks, clear governance standards, and independent oversight. Without these, research risks becoming reactive rather than anticipatory, always responding to harms after they have already occurred.

Another concern is how responsibility for harm is allocated. Much of the dominant discourse continues to place the burden on individuals: encouraging self-control, informed choice, and personal resilience. While these concepts have a place, they are often deployed in ways that deflect attention from structural drivers such as product intensity, marketing saturation, and affordability.

My work challenges the idea that harm can be effectively managed through voluntary measures alone. Evidence suggests that information-based tools and self-exclusion schemes benefit a subset of users but do little to reduce population-level harm. A preventive approach must engage with product regulation, exposure limits, and environmental controls.

Looking ahead, I believe gambling research must evolve in several key directions.

First, we need better early-warning indicators of harm. Waiting until individuals meet diagnostic thresholds is too late. Research should focus on patterns of escalation, financial strain, and behavioural markers that signal emerging risk.

Second, product-level risk assessment should become a standard part of regulatory decision-making. Not all gambling products carry the same risk, yet regulation often treats them as broadly equivalent. Understanding how design features influence harm is critical.

Third, greater attention must be paid to inequality and cumulative harm. Gambling-related harm compounds existing social disadvantage and can exacerbate poverty, mental health problems, and family stress. Research must reflect these dynamics rather than treating harm as evenly distributed.

Finally, the future of the field depends on maintaining independence, transparency, and public trust. Gambling research operates in a contested space, and credibility is easily lost if researchers appear aligned with commercial interests or political agendas.

I see the role of research not as opposing gambling per se, but as ensuring that policy decisions are informed by robust evidence and guided by public health principles. The ultimate goal is not simply to document harm, but to contribute to systems that prevent it.
