He creates installations inspired by the structure of buildings and the surrounding environment, and renders time as a phenomenon that can only be established on site in art museums, museums, alternative spaces and the outdoors. In terms of performances, he has presented tour works that invite the audience to unfamiliar places, stage works that focus on the function of the theater, and choral projects that do not have a central point.
