Ania Catherine (b.1990, US) and Dejha Ti (b.1985, US) are an artist duo whose collaborative practice, Operator, develops critical and conceptual approaches to experience. With Ti’s background as a multimedia artist and HCI technologist, and Catherine’s as a choreographer and performance artist, they engineer medium-agnostic output, joining environments, technology, and the body. Their exploration into privacy began with their installation On View (2019), commissioned by SCAD Museum of Art, and continues with the Privacy Collection, a durational release of works exploring the tension between privacy and transparency in blockchain technology. Operator has created two architectures for choreographic preservation and transactability: the Operator Generative Choreography Method (2023) and the Performance Operating System (2026).

Operator has been awarded The Lumen Prize (Immersive Environments in 2021 and Generative Art Award in 2023), Prix Ars Electronica Honorary Mention (2026), ADC Awards (Gold Cube), and S+T+ARTS Prize Honorary Mention (2021). They have spoken at events and institutions including University of Cambridge, Art Basel, ZKM, Christie's Art+Tech Summit, Bloomberg ART+TECHNOLOGY and MIT Open Doc Lab.
