We invite poster submissions for the Foundations of Ethical AI Workshop 2026 on fairness, trustworthiness, robustness, explainability, and privacy. The poster session during the workshop aims to bring together a diverse community of researchers and practitioners advancing impactful work in responsible, safe, and trustworthy AI. We welcome submissions from all relevant areas, including algorithmic, human-centered, legal, philosophical, sociological, statistical, and theoretical perspectives on ethical AI. Posters will be selected based on novelty, clarity, and their potential to stimulate meaningful discussions during the workshop. Upon acceptance of the poster, at least one author will register, attend the workshop, and present the poster.
