For her cross-cultural work, Dr. Collier uses Community-based Participatory Research (CBPR) models with indigenous people and refugees. Dr. Collier is actively developing projects that are relevant to both Pacific Islanders and Native American people to change health behaviors. She also studies the role of arousal and engagement in mood-repair and rejuvenation; this has been applied to her research with textile handcrafts in women, art-making, the do-it-yourself (DIY) and “Maker” movements.
