She studied religion and English literature at UCLA and taught high school English in Los Angeles before earning her MDiv and PhD from Princeton Theological Seminary. Her research interests include 1 Peter, the Letters of John, and the formation of early Christian identity, with an emphasis on Asian American, intersectional, feminist, and social-scientific approaches to biblical interpretation.
