In my current research I am pursuing an integrated theory, combining Micro- and Macro-Economics, Information Economics, as well as Algorithmic Methodology, in order to understand the Internet and the practice of e-Commerce. 

My current focus has been in the study of Computational efficiency as a bounded rationality concept for economic problems; this is an area commonly referred to as Algorithmic Game Theory.

Other research interests include approximation and on-line algorithms, combinatorial optimization, information retrieval and Internet security.
