Dr. Figueroa focuses her research on developing and testing personalized digital health tools to help individuals lead healthier lives. She focuses on tailoring these tools to the needs of underserved populations, such as people from ethnic and gender minority backgrounds, low-income individuals, and those with severe mental illness. Among other projects, she studies mobile apps that use artificial intelligence to help individuals manage their mental health and increase their physical activity. She developed frameworks to conduct digital health research through a social justice and feminist intersectionality approach.
