She uses contemporary social theory to explore subjectivity, embodiment, and gender. Her research examines social, cultural, and technological transformations in parenthood and families, and the impact of gender, sexuality, race, class, environmental pollution, and geography on care work and human reproduction. Her current research investigates emerging practices of human milk exchange, investigating how care and compassion are harnessed in the commercialization of human milk, and what kinds of relationships are created between donors and recipients. She also explores the ethics and politics of breastfeeding, developing a poststructuralist feminist theorization of breastfeeding as both embodied and relational.
