An ongoing challenge within the diverse HCI and social computing research communities is understanding research ethics in the face of evolving technology and methods. Building upon successful town hall meetings at ACM conferences including CSCW, CHI, GROUP, and IDC, this panel will be structured to facilitate audience discussion and to collect input about current challenges and processes. It will be led by members of the SIGCHI Research Ethics Committee. We will pose open questions and invite audience discussion of practices centered around issues such as recent changes to regulatory requirements (GDPR, US Institutional Review Boards), and cultural and disciplinary differences in ethical practices. There will also be discussion of how research ethical issues should be handled in SIGCHI paper submission and review processes, and how we might create and disseminate ethics resources.
