Thater's work explores the temporal qualities of video and film while literally expanding it into space. She is best known for her site-specific installations in which she manipulates architectural space through forced interaction with projected images and tinted light, such as knots + surfaces and Delphine in the Kulturkirche St. Stephani and the Kunstmuseum Stuttgart. Thater's primary interest lies in exploring the relationship between humans and the natural world and the distinctions between untouched and manipulated nature. Despite nods to structural film, Thater's underlying reference points are closer to panoramic landscape painting. Thater's stated belief is that film and video are not by definition narrative media, and that abstraction can, and does exist in representational moving images.
Delphine
Delphine is one of Thater's most well-known works and was exhibited not only within the United States, but also in several different locations around the world, including France, Germany, Switzerland and Austria. The Delphine exhibition consists of simultaneous projection of multiple footages of underwater and dolphins. The footages are projected on various surfaces, not just the walls, to create an enveloping and engaging space for the viewers. Thater also placed the projectors in a way that the viewer's silhouette created due to the projector light can physically be part of the work and interact with the subjects within her footages. Unlike some films or videos dealing with animals, Thater's Delphine does not include narration. Thater left out narrations and avoided inserting specific narrative because she believes that animals do not live their lives narratively. Thater wanted to show the animals as they are without enforcing human perspective on them.
Science, Fiction
Exhibited in 2015, Thater's Science, Fiction is a video installation that is divided into two parts. The two parts are placed in separate rooms, but both rooms have blue hue due to the light beams attached on the floor corners. The first part consists of two monitors, facing each other, showcasing footages of planetarium from Griffith Observatory, which is located in Los Angeles. The second part consists of huge box, size of a small room, that has a projection of dung beetles above it and intense yellow light under it. The purpose behind this exhibition was to visually show the recent scientific discovery that dung beetles use starlight during night time to navigate themselves. Through her exhibition, Thater commented on impact of light pollution on wildlife.
Chernobyl
First exhibited in 2011, Thater's Chernobyl showcases multiple footages recorded in Prypiat in Chernobyl. The exhibition consists of simultaneous display of multiple footages of different locations in Prypiat. The center of the exhibition is the footage of a movie theater and all four sides of the movie theater are projected on the gallery space. Over the projection of the movie theater, the other footages, such as buildings, animals and nature, are projected as well. This exhibition is not only about showing negative human impact on nature, but to also show how life still persists even under such condition.
In 2011, Thater received an Award for Artistic Innovation from the Center for Cultural Innovation in Los Angeles. She used the grant to complete Chernobyl, a large-scale installation project which documents the post-human landscape at the Chernobyl nuclear power plant site in the Ukraine, marking the 25th anniversary of the explosion in 2011. She has been the recipient of other notable awards, including the Phelan Award in Film and Video, a John Simon Guggenheim Memorial Foundation Fellowship, an Étant-donnés Foundation Grant, and a National Endowment for the ArtsFellowship.
