mark j diaz Hi! I’m Mark, a Ph.D. student in Technology & Social Behavior at Northwestern University. My recent work has focused on technology in low-income Chicago neighborhoods and I have become particularly interested in individuals’ trust in both ‘smart’, or data-driven, technological systems as well as in the institutions developing and introducing these new technologies. I aim to understand how people understand and come to trust and adopt complex, data-driven systems.

My past work has included a systematic analysis of age-related bias in sentiment analysis algorithms as well as a content analysis examining how older adult bloggers discuss and respond to age discrimination. I have previously studied the influence of racial stereotypes in interracial, online collaboration. I currently sit in the Collaborative Technology Lab where I am working with Darren Gergle.

Before beginning my doctoral work, I worked in Accenture Tech Labs developing virtual reality mobile applications and worked as a research assistant and virtual reality programmer studying identity in the Virtual Human Interaction Lab with Jeremy Bailenson at Stanford University (VHIL).
