She is also a member of the Governing Board of the COIT-AEIT and of the Technical Area Committee on Visual Information Processing of EURASIP.

Lucía Tallero is part of the XR Lab team at Nokia Spain, where she develops immersive virtual reality applications using Unity. Passionate about interactive experiences and emerging technologies, she previously graduated with a degree in Video Game Design and Development from Rey Juan Carlos University in Madrid.

Telmo Zarraonandia is an Associate Professor at Universidad Carlos III de Madrid (Spain). Telmo's research primarily focuses on exploring the potential of immersive technologies to support education and designing tools to eliminate obstacles to their widespread adoption by non-experts. He is a member of the committee of the group of Educational Games and Simulations of the Spanish Chapter of the IEEE Education Society, and of the IEC evaluation group SEG 15 Metaverse.

Elena Márquez Segura is a Beatriz Galindo Distinguished Researcher at Universidad Carlos III de Madrid (Spain). She has a multidisciplinary background and works at the intersection of Interaction Design (IxD), Human-Computer Interaction (HCI), and Games and Play. In particular, her work centers on embodied design methods; and on designing and studying technology-supported physical and social experiences, many of which in the realms of games and immersive technologies.

Mario Montagud is a Senior Researcher (Ramón y Cajal fellow) and Part-Time professor at University of Valencia and i2CAT Foundation. He is (co-)author of over 100 scientific publications, has contributed to standardization within different organizations, and has participated in many research projects. His topics of interest include Next-generation Networks, Interactive and Immersive Media (e.g., Virtual/eXtended Reality), Accessibility, Human Computer Interaction (HCI) and Quality of Experience (QoE).

Sergio Cabrero leads the Interactive Media Technology research line at Vicomtech, a technology center specialized in Artificial Intelligence, Visual Computing and Interaction. Previously, he worked at IBM, CWI, and Universidad de Oviedo. He investigates multimedia, distributed and interactive systems applied to different verticals such as culture, media, industry, security, or mobility. He currently leads projects in XR, volumetric media, and media orchestration.

Ana Serrano is an Assistant Professor at Universidad de Zaragoza (Spain). She received her PhD in Computer Science in 2019 (awarded with one of the Eurographics 2020 PhD awards) and she was elected as Eurographics Junior Fellow in 2022. Her research spans several areas of visual computing, with a focus on applying fundamental knowledge about the perceptual system to improve image generation techniques and achieve more realistic and immersive content.
