The EU H2020 programmes emphasises the importance of ethics in all forms of research. The MaTHiSiS consortium has adopted a set of procedures dedicated to ensure that both its activities throughout the project and the final output, a new technological ecosystem, comply with and respect recognised standards of research ethics. Hence, the MaTHiSiS Ethical Advisory Board (EAB) is the advisory body tasked to follow and closely monitor the project activities that could raise ethical issues. The EAB consists of 7 members, impartial, objective and free of any conflict of interest.
