In her current work, she examines individual differences in socializing behaviors (e.g., texting, calling, using social media apps, in-person conversations), and links these behavioral patterns to psychological characteristics (e.g., personality traits) and life outcomes (e.g., well-being). She is also studying whether smartphone-based self-tracking of thoughts, feelings, and behaviors can promote self-insight and positive changes in behavior.
Harari takes an ecological approach to conducting her research, emphasizing the importance of studying people in the context of their everyday environments. To that end, she conducts intensive longitudinal field studies that combine methods from the social and computer sciences (e.g., surveys, experience sampling, mobile sensing, longitudinal modeling, data mining).
