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 and extractive technologies 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. For their seminal work Human Unreadable, they created an on-chain generative choreography method.

Operator has been awarded The Lumen Prize (Immersive Environments in 2021 and Generative Art Award in 2023), HOFA x Phillips Digital Art Award, ADC Awards (Gold Cube), S+T+ARTS Prize (Honorary Mention), and MediaFutures (a European Commission funded programme). They have spoken at events and institutions including Christie's Art+Tech Summit, University of Cambridge, Art Basel, ZKM, Francisco Carolinum Museum, Bloomberg ART+TECHNOLOGY, and MIT Open Doc Lab.
