My work investigates the design and analysis of computer agents that can make good decisions when they interact with other people, and with other computer agents, in domains such as negotiation, game playing, and education. I am a participant in the Colored Trails project, a general test bed for investigating human-computer decision-making. My C.V. can be found here.

The Artificial Intelligence Group (AIRG) at BGU.

Office hours: Tuesday 17.00-18.00.

I am looking for motivated  students who are interested in pursuing graduate studies in the topic of human-computer negotiation (see this link for a description in Hebrew).
