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.
I graduated Harvard university with a PhD in Computer Science in
2006, and an
M.S. in Computer Science in 2002. I did my undergraduate studies at Bar Ilan University, Ramat Gan,
Israel. My C.V. can be found here.
Here is
a tutorial presentation on graphical
models for
multi-agent decision-making that I presented with Avi Pfeffer at AAMAS
2007 (pdf version).
