I study complex human systems: how people interact, make decisions, and adapt when technology, uncertainty, and time shape their choices.
In my research on human–AI collaboration, I examine what changes in people when an AI system becomes part of the team. How does a group generate ideas with a language model in the room? How does trust change when a teammate is a machine? And how do professionals preserve, and redefine, their expertise? I am particularly interested in human–AI decision-making under pressure, including in medical settings.
I also study absence: the gap between what is expected and what is actually observed. Absence can contain important information, but conventional analyses often overlook it. I developed two information-theoretic methods that transform data so consequential absences can be detected and used in analysis.
A third strand of my research examines how interactions unfold over time. Social and organizational interactions have rhythms, and those rhythms can shape collective outcomes. In our work on temporal networks and community dynamics, we showed that the timing of interactions within a community can influence how a disease spreads, sometimes more strongly than differences in the pathogen itself. I presented this research in a keynote at NetSciX 2025 and, more recently, at SigmaPhi 2026.
I chair the ACM IUI Steering Committee and serve as an Associate Editor at ACM Transactions on Interactive Intelligent Systems. I hold a Ph.D. in Computer Science from the Hebrew University of Jerusalem, and an M.Sc. and B.Sc. from the Technion. Prospective students: please see the lab page and get in touch.
