Niloufar Salehi is an Assistant Professor at the School of Information at UC, Berkeley, with an affiliated appointment in EECS. Her research interests are in social computing, participatory and critical design, human-centered AI, and more broadly, human-computer-interaction (HCI). Her work has been published and received awards in premier venues in HCI including ACM CHI and CSCW. Through building computational social systems in collaboration with existing communities, controlled experiments, and ethnographic fieldwork, her research contributes the design of alternative social configurations online.

My group studies and designs social computing systems. Ongoing projects:
How can we make machine translation tools more adaptable to a user context and needs?
How might we design student assignment algorithms to better align with community values?
What would a Restorative and Transformative Justice approach to moderation and governance of online platforms look like?
Student assignment algorithms were designed to meet school district values based on modeling assumptions (blue/top) that clash with the constraints of the real world (red/bottom). Students are expected to have predefined preferences overall schools, which they report truthfully. The procedure is intended to be easy to explain and optimally satisfies student preferences. In practice however, these assumptions clash with the real world characterized by unequal access to information, resource constraints (e.g. commuting), and distrust.
Across the United States, a growing number of school districts are turning to matching algorithms to assign students to public schools. The designers of these algorithms aimed to promote values such as transparency, equity, and community in the process. However, school districts have encountered practical challenges in their deployment. In fact, San Francisco Unified School District voted to stop using and completely redesign their student assignment algorithm because it was frustrating for families and it was not promoting educational equity in practice. We analyze this system using a Value Sensitive Design approach and find that one reason values are not met in practice is that the system relies on modeling assumptions about families’ priorities, constraints, and goals that clash with the real world. These assumptions overlook the complex barriers to ideal participation that many families face, particularly because of socioeconomic inequalities. We argue that direct, ongoing engagement with stakeholders is central to aligning algorithmic values with real world conditions. In doing so we must broaden how we evaluate algorithms while recognizing the limitations of purely algorithmic solutions in addressing complex socio-political problems.
