Between 18th-22nd of November dr Joanna Stępień participated in Brussels in the evaluation of scientific projects as an external expert under the Framework Program for research and innovation Horizon 2020. The projects concerned innovative ideas to improve people’s health and well-being, taking into account environmental, climatic and socio-economic factors. Dr Joanna Stępień worked in a group of 14 experts from various European countries on the substantive assessment of nearly 50 projects. An unquestionable value of work among representatives of different scientific disciplines who share a common interest in the subject of public health is the exchange of opinions from the point of view of various research approaches and the ability to develop a consensus having initially different opinions.
