I study information marginalization, trust, and safety in health and learning institutions (libraries and education) and online, with a special focus on maternal health equity and disability justice. My current work focuses on risk, harm, and marginalization in sociotechnical information systems. I research and support marginalized people' use of defensive information behaviors and institutional efforts to reduce harm related to data and information. 

I am an Associate Professor, and director of the Community Equity Data & Information Lab at the College of Information Studies at the University of Maryland at College Park.

I am also the a faculty affiliate with the Center for Information Technology and Public Life and Center for Critical Race and Digital Studies. I am also a researcher with the Postnatal Patient Safety Learning Lab.
