Joanna Phillips joined the museum in 2008 and focuses on the conservation of time-based media artworks, which include video, film, audio, and computer-based works. At the Guggenheim, Phillips has launched a media art conservation lab and is developing and implementing new strategies for the preservation, reinstallation, and documentation of media artworks. She lectures and publishes on this topic internationally. Phillips has carried out the research, treatment, and documentation of numerous collection artworks, including works by Nam June Paik, William Kentridge, Marina Abramović, Tacita Dean, and Francis Alÿs.
