Agnieszka Mastalerz graduated from the Studio of Spatial Activities of Mirosław Bałka at the Academy of Fine Arts in Warsaw in 2018. She was a guest student of Candice Breitz and Eli Cortiñas at Hochschule für Bildende Künste in Brunswick (DAAD scholarship for 2019/20) and of Adam Broomberg and Oliver Chanarin at HFBK in Hamburg (2017/2018). 

In her artistic practice she puts focus on mechanisms of control and processes influencing and exploiting an individual. She uses a poetic visual language to analyse restrictive rules established within intimate relationships, communities, states, companies and towards the natural environment. Rooted in research, her practice is primarily video-based, often integrating scientific imaging techniques and performative elements.

Mastalerz has recently exhibited at Królikarnia — the National Museum in Warsaw, Krupa Art Foundation in Wroclaw (2025), Catinca Tabacaru Gallery (2024), NS-Dokumentazionszentrum in Munich (2023), MOCAK – Museum of Contemporary Art in Krakow, Manifesta 14 Prishtina, eastcontemporary gallery in Milan (2022), Fabbri Schenker Projects in London, MAXXI – National Museum of 21st Century Art in Rome, Center for Contemporary Art Luigi Pecci in Prato (2021), Wschód Gallery in Warsaw (2020), Palazzo Strozzi in Florence, Starak Family Foundation in Warsaw (2019), Deichtorhallen in Hamburg, Fondation Hippocrène in Paris (2018), Museum of Modern Art in Warsaw (2017 – laureate of the Hestia Artistic Journey Competition), and TRAFO Center for Contemporary Art in Szczecin (2016).
