Are you interested in sensory and consumer science? Are you motivated to have an impact on policy making and regulation of youth-appealing beverages containing psycho-active compounds, such as energy drinks, alcopops and seltzers? We are looking for an excellent and motivated PhD candidate to join WUR and RIVM to work on sensory properties of youth-appealing flavoured beverages related to appeal and consumer behavior, to discourage their use in the Netherlands and worldwide.
What will you be doing?
In the past decades there has been a proliferation of many new reinforcing harmful products (RHPs) that are being widely consumed by vulnerable consumer groups at key stages of their development. Examples include ‘starter drinks’ such as alcopops and seltzers, and energy drinks that contain high levels of caffeine that raise health concerns including increased blood pressure, sleep disturbance, and mental health problems such as anxiety. Together, RIVM and WUR are working to support forward looking policy measures to discourage RHP use worldwide.
You will study youth-appealing flavoured beverages with or without psycho-active compounds: alcoholic drinks including ‘starter drinks’ and 0% alcoholic drinks, caffeine-containing beverages (energy drinks, flavoured and bubble teas, canned ice coffee), and soft drinks. All these RHPs are available in striking, colourful packaging, and contain high levels of sugars or sweeteners and flavourings. You will focus on the effect of additives and packaging on liking of these products that are formulated to create heightened hedonic appeal, and subsequent initiation, conditioning, and continuation of use.
Your work will include perceptual, behavioral studies to examine sensory properties and additives of RHPs, but also quantitative and qualitative consumer studies on knowledge, attitudes and risk perceptions of these products. You will also carry out database and analytical-chemical studies on appeal-increasing additives in these products. Based on your results, you will provide the Dutch Ministry of Health and the World Health Organization with the evidence-base for public communication and regulation of these products.
Your duties and responsibilities include:
- Design and execute analytical, sensory, behavioral and consumer studies
- Analyze data and publish findings in peer-reviewed journals
- Collaborate with universities and other partners worldwide as needed
- Supervise students and take part in educational duties
- Develop yourself to an independent researcher
You will work on two different locations, and have the opportunity to profit from expertise at both RIVM and WUR. Your work will be multidisciplinary, and you will cooperate with many team members. You will forward worldwide policy making and contribute to healthier future generations.
Your working environment
You will be positioned at the Centre for Health Protection | RIVM, Department for Chemical analysis, Tobacco and Drugs. You will work in close collaboration with the Sensory science and Eating behavior chairgroup of the Division of Human Nutrition and Health at Wageningen University ((Sensory Science and Eating Behaviour Group - WUR).
At the National Institute for Public Health and the Environment (RIVM), more than 2,500 colleagues work together every day on good care, a healthy lifestyle, safe products and a safe and healthy living environment. The Center for Health Protection studies the health effects and risks for humans of chemical and biological agents. You will work in particular with the Chemical Analysis, Tobacco and Drugs (CTD) department. We support the policies of various ministries and regulators in the field of tobacco products and drugs and conduct general analytical chemical research. About 30 RIVM colleagues conduct laboratory and desk research here to properly assess the quality and risks of the use of certain products and substances. There is an informal atmosphere in this department and there is a lot of collaboration on projects. Everyone's expertise and individuality is respected. We are used to working across departmental boundaries.
The mission of WUR is to explore the potential of nature to improve the quality of life. Within Wageningen University & Research, nine specialized research institutes from the Wageningen Research Foundation and Wageningen University have joined forces to help answer the most important questions in the domain of healthy food and living environment.
With approximately 30 locations, 6,500 employees, and 12,000 students, it is one of the leading organizations in its domain worldwide. An integrated approach to problems and the cooperation between various disciplines are at the heart of the unique approach of Wageningen. We have been named Best Employer in Education category 2019-2020.
You will enrol in a graduate school (Home - Vlag Graduate School) that provides you with a research and education program of academic excellence.
