Recent projects include analyses of inter-relationships between alcohol consumption patterns and health problems from a life-course perspective and health disparities related to alcohol. He is also involved in projects addressing alcohol’s harm from other use, evaluating impacts of policies targeting drinking during pregnancy, estimating disparities in alcohol policy responsiveness, disentangling economic influences on alcohol-related suicide risk and building agent-based simulation models of population alcohol use over the life course for policy testing.

Robin Purshouse

University of Sheffield, U.K.

Robin Purshouse, Ph.D., is a Professor of Decision Sciences at the University of Sheffield. He led the CASCADE project that developed the foundational microsimulation methods and tools now being used and extended in SIMAH.

Dr. Purshouse’s research focuses on the development and application of advanced quantitative methods for informing population health policy. He has expertise in dynamical systems modelling, particularly exploring how agent-based models, capturing the bidirectional relationships between individuals and social structures, can explain change and stasis in population health outcomes over time.

Dr. Purshouse is interested in how psychosocial theories and evidential uncertainty can be incorporated into computer models to both explain and estimate the effect of policy. He has pioneered machine learning methods that fuse theory with data to discover competing explanations for observed long-term population trends in alcohol use in the USA.

Dr. Purshouse holds an MEng in Control Systems Engineering (1999) and a Ph.D. in Control Systems (2004). Before returning to academia in 2008, he worked as a management consultant at PA Consulting Group. He was the recipient of an ESRC Future Research Leaders award (2012-2014). He teaches undergraduate and postgraduate courses on agent-based modelling and decision systems at the University of Sheffield.

Nina Mulia

Alcohol Research Group, U.S.

Nina Mulia, DrPH, is a senior scientist and associate director of the National Alcohol Research Center at the Alcohol Research Group (ARG), Public Health Institute in Emeryville, California.

She specializes in racial, ethnic and socioeconomic disparities in alcohol consumption, problems and access to alcohol services, and utilizes quantitative and qualitative methods in her research. Her most recent studies have examined longitudinal associations between life course socioeconomic conditions and subsequent alcohol use patterns, and the effects of health care reform on alcohol treatment utilization in racial and ethnic groups.

Before joining ARG, Dr. Mulia was involved in HIV prevention and intervention research with drug users. She studied behavioural biology (BA) at the Johns Hopkins University, Public Health Policy and Management (MPH) at the University of Michigan, and completed a DrPH in Community Health Sciences at the University of California at Berkeley.

Charlotte Buckley

University of Sheffield, U.K.

Charlotte Buckley, Ph.D., is a Research Fellow at the University of Sheffield. Her research is focused on the development and utilization of advanced quantitative methods to understand and explore population-level health behaviours. She has developed a dynamic microsimulation model of population alcohol use in the United States and has used this to explore the relationship between alcohol use and liver cirrhosis. This model is being extended to the SIMAH project, to investigate associations between socioeconomic inequalities, alcohol use and mortality.

Before joining the University of Sheffield, Dr. Buckley received her Ph.D. from the School of Psychological Science, University of Bristol. Her wider interests are in incorporating psychological factors into complex systems models of health behaviours and outcomes.

Aurélie Lasserre

Addiction Medicine, Lausanne University Hospital, Switzerland

Aurélie M. Lasserre, MD, Ph.D., is a physician-scientist working in addiction medicine at the Department of Psychiatry of the Lausanne University Hospital. Her research focuses on the social determinants of mental health, specifically how socioeconomic status impacts alcohol use disorders, depression and suicide. She completed her postdoctoral fellowship at the Institute for Mental Health Policy Research at CAMH and maintains an ongoing collaboration with them. Previously, during her Ph.D. at the Swiss School of Public Health, she investigated how the subtypes of depression and cardiometabolic risk factors, especially obesity, were interrelated in a population-based cohort, taking into account lifestyle factors. As a clinician, she is a trained psychiatrist and psychotherapist with expertise in treating individuals with comorbid substance use disorders with other mental disorders.
