Yoram Bachrach
RESEARCHER
.
I am a researcher in the Online Services and Advertising group in Microsoft Research Cambridge UK since 2009. I got my Ph.D from the Hebrew University, Jerusalem Israel in 2008, and was extremely lucky to have Jeff Rosenschein as my supervisor.
My research area is artificial intelligence (AI), focusing on multi-agent systems and computational game theory. Computational game theory combines the theoretical foundations of economics and game theory with creative solutions from AI and computer science. It is a very active interdisciplinary research area with an immense potential impact on science and industry.
You can find a list of my recent publications below.
