Gloria Mark is a professor of informatics at the University of California at Irvine. Her research examines how individuals, groups, society and technology mutually influence each other. She is particularly interested in studying how information technology use affects multi-tasking, attention, mood, and above all, stress. To study people and their technology use, she employs a method called precision tracking, which involves a combination of sensors, bio-sensors, experience sampling, surveys, and ethnographic techniques to gain a very detailed, comprehensive, and in-depth understanding of what people experience when they use computer technology. Dr. Mark studies real-world technology usage in the workplace and also with college students, who are of the Millennial Generation, who grew up with the Internet. She also studies how people use social media and computer systems to be resilient during and after environmental crises.
