Mr Triantafyllos Pliakas
in Statistical Epidemiology
15-17 Tavistock Place
Triantafyllos has a degree in Nutrition & Dietetics from the Technological Educational Institute of Thessaloniki, Greece. After running his own private practice for three years as a nutritionist and dietitian he moved back to academia to complete an MSc in Human Nutrition (Public Health) at London Metropolitan University and undertake a PhD in environmental epidemiology at the School.
Triantafyllos is involved in teaching on the distance learning programmes at the School. He is the Module Organizer on the distance learning module Environmental Change and Global Health Policy in the MSc in Global Health Policy. He has previously acted as a distance learning tutor on Environment, Health and Sustainable Development, Environmental Epidemiology, Environmental Health Policy and Basic Epidemiology in the MSc in Public Health.
Triantafyllos has also previously contributed to the in-house teaching. He taught on the Nutrition-Related Chronic Disease module in the MSc in Nutrition for Global Health and has been a Lead tutor in the Basic Maths Support Sessions and the PASS scheme in Basic Statistics for PHP.
Triantafyllos has a background in public health nutrition and environmental epidemiology and 14 years of working experience in academic and non academic settings as a public health nutritionist and dietitian, epidemiologist, data analyst and local policy evaluation analyst.
Triantafyllos has been working in academia the past 10 years and his main area of research and work has been on evaluating the impact of the physical/built and food/alcohol environments on health outcomes and behaviours. He has a particular interest in applying quantitative approaches and undertake methodological work on using natural experiments to undertake impact policy evaluations.
Previous research included the use of neighbourhood audit tools and Geographical Information Systems to collect environmental data for the Well London RCT study (PI: Mark Petticrew) and the MRC funded Older Peoples’ Environments and Cardiovascular Risk (OPECR) study (PI: Karen Lock). These studies looked at the effects of neighbourhood environments on diet, physical activity, smoking, alcohol intake and cardiovascular risk in the UK. Triantafyllos also looked at the impact of objectively measured environmental factors on different types of physical activity in English adults using data from the Whitehall II study and the Health Survey for England. Triantafyllos was also a member of the SPHR@L team working within the Alcohol stream. He led two impact evaluations in the areas of alcohol policy; the quantitative analysis of alcohol retail sales data as part of the 'Reducing the Strength' initiative and licensing, on-license alcohol retail sales and crime and anti-social behaviour data as part of the Cumulative Impact Policy evaluation.
Triantafyllos is currently the lead statistical epidemiologist on the 3-year Stigma Ancillary study funded by the National Institute of Mental Health (PI: James Hargreaves). The study is part of the 5-year PopART (HPTN071) cluster randomised trial in Zambia and South Africa that aims to reduce the number of new HIV infections by employing community workers to distribute a combination HIV prevention package that includes early initiation of antiretroviral treatment for HIV infection. The Stigma Ancillary study investigates how HIV-related stigma and other social factors in communities and health settings are affected by, and affect, the implementation of the prevention package. Triantafyllos is also a member of the DFID-funded consortium “STRIVE Tackling the Structural Drivers of HIV” that looks at how the social epidemiology and social determinants of HIV infection are changing over time.
