Her current series, By Her Side (2022–2024), photographs the trees that stood witness to the lives of twenty-five pioneering American women — among them Emily Dickinson, Georgia O'Keeffe, Toni Morrison, Ruth Asawa, Agnes Martin, and Imogen Cunningham. The resulting cyanotypes function as photographic blueprints: evidence of presence, proximity, and time. Her monograph of the same name was published in 2025. Mending, her most recent body of work, extends this inquiry by upcycling and repairing cyanotypes with hand-sewn, plant-dyed embroidery — drawing on Hungarian women's handwork traditions and the Japanese philosophy of kintsugi to explore resilience, repair, and the transmission of creative lineage.
