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.
