Sarah Casey makes drawings which probe the limits of visibility and material existence. She often works with researchers in the sciences and with museum collections, resulting in drawings that are contingent on time and environmental conditions. This practice is led by asking how the drawn mark might embody shared concerns around precarious durabilities. Solo exhibitions of her work have been held at Kensington Palace, The Bowes Museum and most recently at Ryerson University, Toronto. She is Senior Lecturer in Drawing and Installation at Lancaster University, UK and co-author of Drawing Investigations: graphic relationships with science, culture and environment (Bloomsbury 2020).
