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 connections between personal assessments of danger or risk and marginalized people's use of defensive information behaviors to protect self, family, and community from institutional harm. 

I am an Associate Professor, associate director of the Information, Policy, and Access Center , and director of the CEDI 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.
